Although diesel engines are considered the best powerhouses for their heavy-duty
capabilities, concerns have been raised because of their emission issues. Alternative
fuels like jet fuels can be substitute to them for improved efficiencies. The Department Of
Defense uses JP8 for their combat vehicles under their Single Fuel Concept for a better
logistic supply chain. However, due to the projected age of depletion of crude oil
reservoirs, synthetic blends are being considered for their abundant availability.
One such blend, SASOL IPK, a Coal to Liquid based fuel prepared by the Fisher-
Tropsch process is considered in this study. This thesis shows results from experiments
conducted on single cylinder PNGV engine to study the effect of intake charge
temperature and injection timing on ignition delay of SASOL IPK. Speed, fuel injection
pressure, swirl ratio and charge density were kept constant for all data points.
Two cases were considered, one with constant SOI and varying intake air
temperature and the other with constant intake air temperature and varying SOI. It was
observed that with an increase in intake air temperature and advancing injection timing,
ignition delay of the fuel reduced significantly. NTC regime and cool flame also decreased
drastically at higher intake air temperatures and advanced injection timing
High-throughput FPGA QC-LDPC decoder architecture for 5G wireless
No full textWireless data traffic is expected to increase by a 1000 fold by the year 2020 with more than 50 billion devices connected to these wireless networks with peak data rates upto 10 Gb/s. The next generation of wireless cellular technology (being collectively termed as 5G) is slated to operate in the mm-wave (30-300GHz) spectrum which comes with challenges such as, reliance on line of sight (LOS) communication, short range of communication, increased shadowing and, rapid fading in time. This will necessitate additional signal processing techniques such as large antenna arrays and beamsteering which will further reduce the processing budget available to the channel coding system. In an effort ort to design and develop a channel coding solution suitable to such systems, in this thesis we propose strategies to achieve a high-throughput FPGA-based decoder architecture for a QC-LDPC code based on circulant-1 identity matrix construction. We present a novel representation of the parity-check matrix (PCM) providing a multifold throughput gain. Splitting of the node processing algorithm enables us to achieve pipelining of blocks and hence layers. By partitioning the PCM into not only layers but superlayers, we derive an upper bound on the pipelining depth with respect to the size of the superlayer for the compact representation. To validate the architecture, a decoder for the IEEE 802.11n (2012) QC-LDPC is implemented on the Xilinx Kintex-7 FPGA with the help of the FPGA IP compiler available in the NI LabVIEW Communication System Design Suite (CSDS). It off ers an automated and systematic compilation flow. An optimized hardware implementation from the decoder algorithm was generated in approximately 3 minutes, achieving an overall throughput of 608Mb/s (at 260MHz). With little or no modi fications, the proposed decoder architecture caters to a wide range of circulant-1 identity matrix construction based QC-LDPC codes widely accepted in several communication and data storage standards.M.S.Includes bibliographical referencesby Swapnil Mhask
Opportunity cost analysis of android smartphones' permissions
No full textThis thesis provides the opportunity cost for reading androids permission model. We investigate the opportunity cost for users and an example nation (United States), if people would actually read these permission screens during installation time.While the Federal Trade Commission and reserachers try to protect users’ privacy and to improve their comfort level with mobile applications, users still remain unaware of these changes. Users are given a choice to overview the permissions an app would use and have to make an on the spot decision to accept these and move forward with the installation. In this research we project the time required by an average user if they were to read the permissions and compute the monetary value of that time in different situations. An average user may spend half an hour in overviewing permission screens bearing maximum opportunity cost of 3 based on whether it was read at work or leisure. Other than this, if the users decide to read the details of these permissions as well, they will spend more time and hence bear more cost. Reading permissions with details would require users to spend two and half hours annually with a maximum cost of 13. An entire nation (United States) would have to invest a minimum of 6 billion, in reading permissions.M.S.Includes bibliographical referencesby Swapnil Sarod

No full textRelationship between Intergenerational mobility (IGM) and economic growth: Evidence from cross-country data
Full text linkInequality of opportunity (IGM) is a major cause of inequality of opportunity in many countries. However, the impact of IGM on economic growth has not been fully explored. In this research project, I first replicated and extended the IMF working paper titled IGM, IGM, and Economic Growth’ by Shekhar Aiyar and Christian Ebeke (2019), which explored the relationship between income inequality and economic growth, utilizing various measures of intergenerational mobility, to confirm that the adverse impact of income inequality on growth is more pronounced when IGM is lower. Then, I used the latest Gini dataset (All the Ginis’) compiled by Branko Milanovic (2019 version). The findings of this paper highlight that reducing inequality can significantly boost a country’s growth, particularly in economies with high inequality of chance (characterized by higher Intergenerational Mobility or low intergenerationally persistence). In countries with low IGM (i.e., higher income elasticity), income inequality more significantly hampers the nation’s economic growth. Therefore, policymakers must not only address income inequality in isolation but also tackle the fundamental causes of inequality

The Development of A Corporate, Marketing, Operations, and Financial Strategy for A Swiss Cosmetics Start-up
Full text linkThe aim of this Group Management Project is to explore the different strategies that can be implemented by a Switzerland based decorative cosmetics start-up business owned by one of the author of this document Mr. Axel Schmidt. The authors of this project Mr. Swapnil Deshmukh and Mr. Axel Schmidt are pursuing their MBA in Finance and MBA in Entrepreneurship degrees respectively and thus have provided insights gained from the overall MBA programme and particularly in their respective specialisations.
The document consists of seven chapters elaborating on corporate, marketing, operations and financial strategies for the start-up business in decorative cosmetics. The Swiss decorative cosmetics industry is characterised by a fierce and turbulent market conditions dominated by multinational cosmetics firms.
The first chapter introduces the authors and their reason and motivation behind this project, the concept of family start-up businesses, outsource production (private label) and the company lipCat Private Limited.
The company lipCat Private Limited will indulge in selling decorative cosmetics products in the low price segment targeting young Swiss women on an online basis focussing only in Switzerland at its nascent stage. However, depending on the success of the business the company aspires to expand its operations to selected European countries.
The second chapter reveals the corporate strategy of the company and includes the analysis of Swiss cosmetics market. Strategic tools such as SWOT, PEST and PORTER’S FIVE FORCES have been employed to gain more insight into the internal and external factors affecting lipCat. It also includes the analysis of its competitors, mentions the values, mission and the vision of the company owners. The chapter also mentions that lipCat will pursue a cost focus strategy based on its existing limited resources.
The third chapter deals with the marketing strategy and defines marketing objectives of the company and underlining the different marketing mix options that lipCat plans to implements during its business operations. One of the major tools used in this chapter is consumer segment analysis, also different marketing steps such as creating an USP, Value proposition and copy strategy and brand personality. It also lays down the marketing budget and the marketing roadmap for lipCat. It also provides for certain marketing strategies that should be specifically implemented by start-up businesses. The fourth chapter exposes the operational activities of the business. It describes the process of the company starting with its purchasing the products from its supplier based in US to selling the products in the local Swiss market.
The fifth chapter divulges the financial strategy of the company. It explore the existing financial structure of the company and how company can finance its future growth and expansion with its limited available resources. It also suggests for specific financial options that a small size business firm can explore to succeed. The chapter also includes and explore different strategic options that the company can explore in order to gain financial advantage. Finally it provides for different exit strategies in case of failure as well as success of the business.
The sixth chapter mentions strategy implementation roadmap for lipCat based on the previous four strategy chapters.
In the seventh chapter we conclude that lipCat as a business has certain negative aspects, such as reluctance of women to purchase decorative cosmetics over the internet and has limited resources to compete in the highly competitive market. However we also believe that the existence of a niche market, high flexibility and very low fixed costs will allow lipCat to exploit its potential in a manner that will yield positive results for the company
