INFORNO operating system Research Proposal Example | Topics and Well Written Essays - 1500 words

INFORNO operating system - Research Proposal Example Here, the term varied computing systems involves not just desktop computers but a range of devices such as palm tops, laptops, set-top boxes and other communication equipment. The challenge in writing applications for a distributed and hybrid environment is threefold: firstly, the development environments vary greatly, secondly, systems and the way these systems present resources vary greatly and finally a varied network has varying security and authorization policies that may not necessarily synchronize across the network (vitanuaova.com, nd). Inferno was developed as a successor of Plan 9 OS primarily with the help of Dennis Ritchie and Ken Thompson in the Bell Labs computing Sciences research centre in New Jersey, USA in 1995 (operating-system.org, 2008). The entire team of INFERNO includes Sean Dorward, Rob Pike, David Pressotto, Dennis Ritchie, Howard Trickey and Phil Winterbottom. The primary motivation behind INFERNO is generating the capability to include a range of everyday use hardware devices into a distributed network. INFERNO OS facilitates the creation and support of distributed services in the new and emerging world of network environments, such as those typified by CATV and direct satellite broadcasting systems, as well as the Internet (Dorward et al 2002). Inferno is designed to accommodate the diverse providers of content and services from equally diverse transport and presentation platforms. From the above discussion it is evident that the main strength of INFERNO lies in its portability across several dimensions. Primarily, it is portable across various processor architectures. Currently it works with Intel x86, Intel XScale IBM Power PC, ARM, SunSPARC and MIPS (vitanuova, nd). Secondly INFERNO is portable across platforms. It can run as either a stand-alone operating system or as an application under the regular operating systems such as Window s and Linux (Dorward, Pike, Pressotto, Ritchie, Trickey and Winterbottom, 2002). Inferno's underlying architecture, the STYX protocol is the reason behind Inferno's interoperability. The protocol has been designed such that all communication is essentially handled through the file system which is very similar to UNIX OS (electronicdesign, 2000). Almost all of the INFERNO's capabilities and functionalities are based on Limbo, which is the programming language of Inferno. The primary reason for choosing Limbo to support INFERNO is because of its ability to support distributed computing. Multi-tasking is supported directly by the Limbo language. It supports multi-tasking with the help of independently scheduled threads that can be spawned, and coordinated which enable communication between tasks. It supports modular programming, strong type checking, interprocess communication, automatic garbage collection and simple abstract data types (Ritchie, 2005). Another motivation behind Limbo is its similarity to commonly used languages such as C and PASCAL (Dorward et al, 1997). So, if one needs to port INFERNO from one hardware or a system to another all one has to do is to modify a few hardware dependent functions. This is how it turns out to be an excellent operating system for all types of hardware and distributed computing. The system can be used to build portable client and server applications

Article analysis Assignment Example | Topics and Well Written Essays - 1250 words

Article analysis - Assignment Example In both scenarios, the business success for both companies and suppliers will depend on the depth and strength of their relationship. This paper starts with an explanation of the common mistakes companies commit in dealing with their suppliers. Several factors that companies should consider before getting a supplier or outsourcing a business process will follow. Different types of supplier relationships are then explored. The paper ends with a discussion of properly managing supplier relationships. 2. Mistakes to avoid in supplier relationships The first mistake that companies commit even before entering into supplier relationships is the lack of organizational/business process analysis. Companies often enter into supplier relationships without first knowing what the company really needs. These â€Å"unevaluated processes† blind a company from the areas where it excels and areas where it needs improvement (Aron and Singh 136). A company, then, might mistakenly outsource core p rocesses which are vital to its functioning, or manufacture in-house those components which can be sourced from suppliers at lower costs with same quality, for instance. Another mistake companies make involves getting into supplier relationships for the wrong reasons. ... Venkatesan talks about the fear of some companies on being â€Å"hollowed out† once they establish a relationship with a supplier (99). These companies fear that sourcing components from suppliers makes their products lose their unique qualities which make them less competitive. While this fear may have a rational basis, companies tend to forget the purpose of getting a supplier in the first place. 3. Factors to consider in sourcing Several factors need to be analyzed first before coming up with a decision of whether or not to source. A thorough analysis of a company’s areas of strength and weakness should be accomplished first. This analysis will help the company determine which processes are vital and, therefore, should be kept in-house, and those processes that don’t necessarily add value to the product and, therefore, are better left at the hands of a service provider or a supplier. Aron and Singh suggest differentiating the â€Å"core, critical, and commodi ty processes† of a business organization (136). Core and critical processes usually involve management and analytical processes while commodity processes are clerical in nature. Venkatesan, meanwhile, differentiates â€Å"strategic and non-strategic components† (100). When it comes to manufacturing companies, the decision to source from suppliers usually come from an understanding of the products strategic and non-strategic components. Strategic components, as decided by management, are those that make the product stand-out from the market. These components have a direct impact on the product’s quality, differentiation, and market position. Non-strategic components, on the other hand, don’t necessarily affect the outcome of the final product. This can be the screws of a DVD player, capacitors

Nano Reinforced Filaments for Additive Manufacturing

Nano Reinforced Filaments for Additive Manufacturing Nomenclature: Summary: Fused Deposition Modelling (FDM) is a popular technique for Additive Manufacturing (AM). FDM is used for fabrication of thermoplastic parts used for rapid prototyping with advantages like low cost and minimal material wastage. The objective of this project report is to understand different properties of reinforced extruded polymer filaments. The process includes the mixing of carbon nanotubes with polymer filament such as PLA and investigating different properties i.e. mechanical properties and use these new filaments for FDM (Fused Deposition Modelling) machines. CNT blended polymers are lighter but stronger materials then typical PLA. This new material has outstanding mechanical properties which includes extreme tensile strength and Youngs modulus. The blending of CNT with PLA is shown in this report through microscopy. The experiment includes PLA with different composition i.e. simple PLA,0.1% CNT,0.2% CNT,0.5%CNT and 1%CNT. The tables show the relationship between shear rate and shear viscosity of materials with different compositions achieved through rheology. The rheological behaviour of CNT composite melt was also examined at two different temperatures i.e. 190 °c and 195 °c. The graph represents the This report is going to present the results achieved by MFI (Melt Flow Index) and Rheology to see if the material is stronger than any typical polymer, so that it can be used for Additive Manufacturing. The technology of Additive Manufacturing (AM) is rapidly emerging as alternative to conventional manufacturing techniques. Industry is increasingly looking at it as a means of producing finished articles rather than simply for prototyping. One of the main AM techniques is Fused Deposition Modelling (FDM) in which a polymer filament is melted and progressively extruded to create a 3D plastic part. AT present a relatively small number of polymers may be successfully used with conventional FDM machines and this is limiting the ability of the process to expand into new markets. 1.1. Additive Manufacturing: Additive manufacturing (AM) is the name given to a group of emerging technologies that create objects from the bottom-up by adding material one cross-sectional layer at a time. [[i]] A three-dimensional solid object of virtually any shape can be manufactured from a digital model. The adaptation of such a technology will result in engineers having to invest less time dealing with manufacturing constrains and will give them almost unlimited design freedom. However, up to now, despite all positive aspects, no single 3D printer has been able to print using different materials. Additionally, while various materials can be used in AM, their material properties, such as strength, electrical conductivity and thermal conductivity typically have inferior properties compared with conventionally manufactured counterparts due to the anisotropy caused by the layer-by-layer approach. Many studies have reported on the incorporation of nanoparticles for the creation of new printing materials for AM. Metal nanoparticles [ii]], Nano-sized carbon black powder [iii]], carbon nanotubesand ceramic nanoparticles have been used in the past. Manufacturers across different industries are utilizing this digital manufacturing procedure to create a range of items, including: motor parts for car applications, impellers and blades for aviation use, design less sand moulds for pumps utilized as a part of the oil and energy industry, and medical prosthetics which require effectively versatile design adjustments. 1.2. Carbon Nano-Tubes: Carbon nanotubes (CNTs) take the form of tube shaped carbon atoms and have novel properties that make them potentially valuable in a wide variety of utilizations in nanotechnology, hardware, optics, and different fields of materials science. They show exceptional quality and one of a kind electrical properties, and are good conductors. Inorganic nanotubes have also been combined. Manufacturing a nanotube is subject to applied quantum science, particularly, orbital hybridization. Nanotubes are composed altogether out of sp2 bonds, like those of graphite. This holding structure, stronger than the sp3 bonds found in diamond, gives the atoms their exceptional quality. Nanotubes adjust themselves into ropes held together by Van der Waals forces. Under extreme pressure, nanotubes can combine, exchanging some sp2 bonds for sp3 bonds, giving incredible probability for creating solid, unlimited-length wires through high-weight nanotube association. [iv] Carbon nanotubes (CNTs) are allotropes of carbon with a tube-shaped nanostructure. Nanotubes have been developed with length-to-distance across proportion of up to 132,000,000:1, fundamentally bigger than for any other material. These round and hollow carbon atoms have abnormal properties, which are invaluable for nanotechnology, gadgets, optics and different fields of materials science and innovation. Specifically, owing to their unprecedented thermal conductivity and mechanical and electrical properties, carbon nanotubes find applications as added substances to various structural materials. For example, nanotubes form a tiny bit of the material(s) in a few (basically carbon fibre), golf clubs, or auto parts. [v] Nanotubes are classified as single-walled nanotubes (SWNTs) and multi-walled nanotubes (MWNTs). Singular nanotubes normally adjust themselves into ropes held together by van der Waals strengths, more particularly, pi-stacking. The theoretical concentration of carbon nanotubes required to reach the electrical percolation threshold for a CNT/Polymer composite can be obtained, as a first step, using the power law: where à Ã†â€™ is the electrical conductivity, à Ã¢â‚¬   is the MWCNT volume concentration in the nanocomposite, is the critical MWCNT volume concentration at electrical percolation, and ÃŽÂ ± is a critical exponent. [vi] The aim of this project is to investigate the use of carbon-nanotubes (CVTs) as a reinforcement in the extruded polymer filaments used in FDM. The intention is to create a new polymer nanocomposite blends that will enable parts produced by FDM to have wider ranges of properties. CNTs have the potential to significantly enhance mechanical properties without significantly increasing the viscosity of the polymer melt and the ease of production of filament and its performance in FDM. Objectives: The primary objective is to find the MFI (Melt Flow Index), the rheological properties of different CNT compositions. The MFI and Rheology tests should show the melt flow index, viscosity and shear rate. With the help of the these tests the viscoelastic properties can determine the mechanical performance of the final products. The results will show how adding carbon Nano-tubes in thermoplastics can change its mechanical properties like tensile strength, yield strength and youngs modulus. 3D printing or additive manufacturing (AM) is any of different processes for making a three-dimensional object of any shape from a 3D display or other electronic information source fundamentally through additive processes in which progressive layers of material are set down under PC control. Early AM hardware and materials were created in the 1980s. In 1984, a procedure created known as stereo lithography employing UV lasers to cure photopolymers by Chuck Hull of 3D Systems Corp. Hull created the STL file format, which is widely acknowledged by 3D printing programming. Metal sintering types of Additive Manufacturing were being created, (for example, specific laser sintering and coordinate metal laser sintering), although they were not yet called 3D printing during 1980s. In 1990, the plastic extrusion innovation most broadly connected with the expression 3D printing was marketed by Stratasys under the name Fused Deposition Modelling (FDM). [vii] Originally created at the Massachusetts Institute of Technology in 1993. 3D printing innovation frames the basis of Z Corporations prototyping procedure. 3D physical models are created by 3DP technology by setting layers of powder deposition utilizing a fluid binder. 3DP technology is versatile and fast processing geometry of extreme complexities in numerous applications, which support different types of material. Z Corp. pioneered the 3DP innovation creating 3D printers that manufacturers use to introduce early concept models and prototypes. Using 3DP innovation, Z Corp. has created 3D printers that work at extraordinary rates, amazingly low expenses, and inside an expansive scope of uses. Additive Manufacturing innovations discovered applications beginning in the 1980s in product improvement, information representation, manufacturing and rapid prototyping Their expansion into generation (job production, large scale manufacturing, and manufacturing) has been being worked on in the decades since. Modern production roles within the metalworking businesses accomplished noteworthy scale without precedent for the early 2010s. [viii] Besides all the advantages of Additive Manufacturing, it has also some disadvantages which includes its slow building rates as printers lay down material at speed of one to five cubic metre per second, parts can only be printed one at a time which can prevent economics of scale and higher production costs. [ix] Fused Deposition Modelling (FDM) is a technology which is based on layers of strands of semi molten thermoplastics placed on top of each other in a 3-dimentional shape. FDM is a developing technology which is currently used in rapid prototyping and manufacturing. FDM is commonly known as an additive process, which is made by expelling material into layers which are controlled by a PC to form the final shape. Some FDM machines permit the client to control different parts of the layering procedure, for example, layer thickness, air hole between extrusions, angles of contour, and extrusion width. These straightforwardly affect the last shapes mass, thickness, quality, solidness and penetrability. [x] AM is creating to meet the demands for sturdy new parts, which need to comply with specific mechanical and design requirement. Along thermal properties, new printing materials must have appropriate rheological and thermal properties to be ready to be extruded and solidify while keeping up the exactness of successive layers. The utilization of polymers in additive manufacturing are represented by the transition of glass temperature, malt viscosity, heat capacity and the shear stress of the material. Understanding the relationship between the basic properties will help in the improvement of advanced printing materials and filaments. The glass transition temperature (Tg) is the temperature beneath which the polymer gets to be weak and hard like glass. The glass transition temperature is not the melting point, that is characterized by the temperature at which crystalline or semi-crystalline polymers transform from its crystal structure to its liquid state. Poly-Lactic Acid (PLA) is a biodegradable and low toxicity thermoplastic which is made up of lactide or lactic acid monomers. Poly (vinyl acetate) PVA is also a biodegradable thermoplastic polymer which is synthesized by the hydrolysis poly vinyl acetate (PVAc) because of tits instability of vinyl alcohol monomer. Polycaprolactone (PCL) is polymerized from caprolactone monomer. PCL is hydrophobic in nature and is soluble in chloroform, which biodegrades in the presence of microorganisms. [xi] Figure 1: PLA, PVA and PCL [xii] 3DXTech is a company that provides filaments containing carbon nanotubes.

For this research, different compositions of CNT polymer are tested at two temperatures i.e. 190 °C and 195 °C. The set of experiments decided for this research were MFI (Melt Flow Index), Rheology and Microscopy. MFI (Melt Flow Index): ISO 1133-1:2011 governs the procedure for the measurement of the melt flow rate. [xiv]] MFI (Melt Flow Index) is a measure of the ease of the melt flow of thermoplastic polymers. It is defined as mass of polymer, in grams, which is flowing through a tube of specific diameter and length by a pressure applied via specific weight. (A.V. Shenoy D, R. Saini 1986). It is an indirect method of measuring molecular weight, with respect to melt flow. MFI is inversely proportional to the viscosity of the melted polymer, [xv]] as the viscosity depends on the specific weight applied. In this test granules of the specimens are packed into a barrel at the bottom of which there is a 2.0955mm diameter 8mm long die. The polymer is heated for a specific period and then the amount, which flows through the die during a specifies time and under a specific mass, is measured. Melt Flow rate used for PLA and CNT are measured at 190 °C and 195 °C. MFI test is a single point test, which only show s a single value on shear rate vs. Viscosity graph. Rheology: The study of polymer rheology testing is to investigate how the stresses in polymers or the applied force is related to the deformation of polymer and its flow. The science of rheology itself is quite complex, however, the rheograms produced by this technique are useful in determining the effect on melt viscosity of temperature. Capillary rheometer consists of a barrel which is temperature controlled incorporating two bores of different diameters. During the polymer melt, the pressure applied through the dies is recorded. [xvi]] The understanding of polymer rheology through laboratory testing can help see the presence of liquid-like behaviour which depends on the applies load. The information collected through rheology can help optimise the material for FDM (Fused Deposition Modelling). As the melt flow depends on the viscosity of the material. The tests are performed when the polymer is going through melt phase. Microscopy: Microscopy is a field of using microscope which helps in viewing objects and areas which cannot be seen through naked eye. The analysis of microscopy provides a mean to study and characterize the micro and Nano-structural features of polymers. [xvii]] In this experiment, an optical microscope is used to observe the structure and chemical composition of CNT with PLA. Microscopy of CNT compositions are compared with simple PLA material. Because of the microscopy, the porosities and blending of polymers can be seen. The technique can be helpful in determination of the causes of failure. Methodology: Figure2: Twin Screw Haake Extruder [xviii] MFI (Melt Flow Index): After turning on the Kayeness Galaxy Melt Flow Indexer a die of 2.0955mm was dropped into the bottom of the barrel. A melt time was set up at 360 seconds and number of cuts as well. In this experiment the number of cuts were 3. Temperature was first set at 190 °C. Once the barrel reached the temperature, the granules of 0.1% CNT + PLA were poured into the barrel periodically packing with the tamping tool to remove the trapped air. Piston was placed into the barrel and a weight of 2160g was placed. In accordance with ASTM D1238-95. Note: Piston rod weighs 100g and this was taken into the account. After the program started the piston starts to drop. High polymers are required a plug to prevent run-out of the polymer during polymer melt period. After melting time was over, Run button was pressed and the extrudate was cut simultaneously across the orifice face. A timer counts the test time on the front panel; it will bleep when it is nearing the end of the melt time. As the number of cuts were 3, step 6 was repeated two more times. The extrudates obtained were then weighed and recorded for finding the value of MFI (Melt Flow Index). Once all the material was purged from the barrel, it was then cleaned with cotton swatches and bronze brush. To get the MFI value of 0.2%,0.5%,1% and 100% PLA, the procedure was repeated for every composition. Another set of values were also obtained at 195 °C by repeating the experiment. The MFI machine used for the experiment is shown below.

The Tragic Merchant of Venice :: Free Merchant of Venice Essays

The Tragic Merchant of Venice      Ã‚  Ã‚  Ã‚  Ã‚   In my opinion the play The Merchant of Venice is a tragic one which is discised as being comic.   Many factors of this play are derived from the current voice of situation.   The Merchant of Venice could be looked at as more tragic because of the negative intents from some of the characters in the play.      Ã‚  Ã‚  Ã‚  Ã‚   Greed and deception are just a couple of the main features from where many of the decisions are derived.   For example, revenge was an intent that Sylock had against for Antonio, only to say the least for, greed...   Antonio is being a set victim for revenge because of his deception against Shylock, and also for prior intent to do.      Ã‚  Ã‚  Ã‚  Ã‚   If The Merchant of Venice was to be looked at as more comic, the scenarios wouldn't be taken as seriously as they should be.   Infact I believe that The Merchant of Venice written by William Shakespeare was officially intended to be so in both comic and tragic.   In depth looking and observing The Merchant of Venice I have seen a small equivalency in the amount of comicness and tragedy in the play.      Ã‚  Ã‚  Ã‚  Ã‚   I have come up with the conclusion that William Shakespeare was a great playwright and must have been an absolute genius to compose the great and wonderful things that he did.   The Merchant of Venice is excellent in it's way of describing the characters.   The emotion is spread out thoroughly like warm butter on hot toast.   The tragedy in The Merchant of Venice is believable and almost true in a sense of my opinion in relating to greed, human desire, and most important let not forget, anguish.      Ã‚  Ã‚  Ã‚  Ã‚   Throughout The Merchant of Venice there are many strong feelings displayed through powerful lines of contemporary nature, to be truthful. William Shakespeare most likely wrote this play The Merchant of Venice to display how human greed could be so consuming to the soul of a person, which he did very well if I may say so.      Ã‚  Ã‚  Ã‚  Ã‚   The spunk and enthusiasm of this play makes it engrossing to the reader or viewer and also keeps the audience engaged in what is going to happen next.

How does Alan Bennett make the audience feel empathy for Doris in A cream Cracker under the Settee?

A cream cracker under the settee is a dramatic monologue written by Alan Bennett in 1987 for television, as part of his Talking Heads series for the BBC. Doris is in her seventies. This hints at her being old and vulnerable in need of care and assistance. Moreover, she outlines that she does not â€Å"attempt to dust†, this is maybe because she is physically unable or consumed by her thoughts. Zulema says that her â€Å"dustings days are over†. This makes you feel sorry for Doris and deeply empathise with her. She may have a fear of dirt – rupophobia or she may just be an exceptionally sanitary person. Furthermore, Zulema exploits Doris' old age and feelings by saying she â€Å"doesn't have the sense she was born with†, this maybe true but it is inconsiderate towards Doris' feelings. Then again, Zulema does have the right to speak her mind, as she has to put up with Doris's nagging all week. Doris is never satisfied with Zulema's housekeeping saying, â€Å"Zulema doesn't dust, she half-dusts† This emphasises Doris obsession with cleanliness, maybe suggesting that she has OCD (Obsessive Compulsive Disorder). Alternatively, maybe occupying her mind with such things helps her forget the melancholy she feels deep within. However, as we progress through the monologue we learn that Zulema in fact intimidates Doris. Ultimately, making Zulema the more dominating character. She does not hesitate in telling Doris â€Å"I am the only person that stands between you and Stafford House.† In spite of this, Doris is adamant that she will not lose her independence and is sure that she will remain in her own home. Another good example of this is when â€Å"she shoves the duster down the side of the chair†. We can only assume that Doris does this to avoid a lecture or confrontation with Zulema, preventing further distress. Again, we feel empathy for Doris as important issues such as treatment of the aged, growing old and life choices are brought to our attention. Therefore, we can conclude that she sometimes feels unhappy and unsettled in her own home. In the midst of all this, the fact remains Doris is suffering from a â€Å"numby† leg. Alan Bennett deliberately places talk about her leg between pauses so that the audience has time to focus on and consider Doris's current situation and therefore feel a great deal of compassion for her. These strategic pauses are used constantly throughout the monologue, giving us plenty to sympathise with. Throughout the monologue, the ending of each scene is indication by the simple stage direction â€Å"Go to black†. This maybe connotes a temporal shift or the passing of time. Moreover, before each scene fades to black, Alan Bennett gives the audience something to ponder over and keep in the back of their heads. For the whole of the monologue, Doris speaks to us directly. This enhances her vulnerability, yet she maybe biased, as we only know her point of view and nobody else's. This leads us to believe that Doris thinks everything revolves around her and she may come across as self-centred or self-obsessed. Then again, we feel great sympathy for Doris as she is isolated, cut off from reality, and maybe unwanted by a society, which considers her as an outsider. The setting changes throughout the monologue, as Doris travels to various parts of her home, nevertheless she remains in the same location. This connotes a very static nature, suggesting that Doris hardly ever goes out and mostly stays in the same room. According to her, â€Å"I never get a bona fide caller†, this tells us the only visitor she probably has is Zulema. We feel great empathy for Doris because she is lonely, lacking a faithful companion. Furthermore, the moving from the comfy position of her settee possibly indicates the movement from a secure and comfy position in life to her current situation. Still, this isolated place is her comfort zone, perhaps signifying that she is more likely to tell the truth as she is under no pressure and can speak of her own free will. Subsequently, she does in fact unravel the truth about various stages in her life. Another clever device Alan Bennett uses to make the audience feel empathy for Doris is humour and Doris certainly has a sense of humour, we realise this when she says, â€Å"Love God and close all gates.† The audience finds it easier to empathise with her because they can laugh with her and not at her. Her dry, sarcastic humour is a hit with audience off all ages. As Doris discusses her husband Wilfred, she talks about him â€Å"getting mad ideas†, stating how absurd they were and how he â€Å"never got round to it†. Yet, according to her, â€Å"A kiddy'd've solved all that†. This makes us wonder why Doris does not have a child and whether she has any family at all. We suddenly feel a great deal of compassion for her because her only family, Wilfred, has passed away. Later on, we discover that she did have a baby, which also passed away. â€Å"If it had lived I might have had grandchildren now,† she explains. Our degree of sympathy for Doris expands to greater lengths. Death is certainly one of Alan Bennett says of gaining empathy for his characters. Further on in the monologue we discover that Doris and Wilfred were not very outgoing people. Doris plainly explains, â€Å"We weren't the gregarious type.† This implies that even when Wilfred was alive, Doris was a secluded, reserved individual. Then she refers to Wilfred, â€Å"he thought he was, but he wasn't†. This gives us the impression that Wilfred could have been a sociable person except Doris stood in his way as she essentially controlled their relationship. We feel empathy for both characters here since they never really experienced anything amazing in their lives; except for grief and now for Doris, loneliness. This could all change though if Doris decided upon leaving home and moving to Stafford House but apparently â€Å"You go daft there, there's nowhere else for you to go but daft† according to Doris. Perhaps Doris is against the idea of leaving home because all her memories of Wilfred will remain there or she might just feel afraid and unprepared to face the real world on her own at a late stage in her life. Towards the end of the monologue, Doris hears the voice of a police officer, enquiring as to why her home lights are off. Instead of asking for his help, she lets him leave. It is assumed by the audience that Doris later dies, because she feels the time is right. Also as the conclusions to Bennett's plays are usually miserable. Her last words are â€Å"Never mind. It's done with now, anyway.† Then the â€Å"LIGHT FADES†, a sense of desperation and sadness fill the readers heart and mind, no greater empathy can possibly be felt for Doris at this stage. This dramatic and powerful text leaves the audience wondering, hoping. This is without doubt Alan Bennett's cleverest writing technique!
