Alkali-free bioactive glass composition, U.S. Patent 9,238,044
The present invention relates to development of bioactive glass/glass-ceramic composition that are able to promote a fast deposition layer of carbonated hydroxyapatite upon immersion in simulated body fluid (SBF) for time periods as short as one hour. Such composition might include fluorides, and a variety of oxides (or their precursor compounds), such as Na2O—Ag2O—SrO—CaO—MgO—ZnO—P2O5—SiO2—Bi2O3—B2O3—CaF2, be prepared by the melt route or by the sol-gel process, with the specific composition and the preparation route selected according to the intended functionalities, which can present controlled biodegradation rate and bactericidal activity. The powders derived from glass melts purred in cold water (frits) may completely densify by sintering at temperatures up to 800° C. without devitrification, resulting in bioglass compacts with high flexural strength (˜85 MPa). The bioactive glass powders prepared by sol-gel densify at lower temperatures due to their higher specific surface area and reactivity
Rent - seeking trade policy : a time series approach
Using a time-series approach, the author analyzes the relationship between the extent of rent-seeking trade policy and both political and economic variables. For rent-seeking trade policy, the indicator he uses is the number of foreign-trade regulations passed each year for the benefit of a single firm or industry. The author uses data from Uruguay for 1925-83. Uruguay, which experienced an impressive economic decline, is an outstanding example of a rent-seeking society. After being a wealthy economy in midcentury, it suffered almost complete stagnation, which led to social and policital disintegration by the end of the 1960s. Three decades of restrictive regulations on foreign trade had created a nearly closed economy by the end of the 1960s. It was worth analyzing whether policymakers'great receptiveness to demands for protection could account for Uruguay's decline. Over the period 1925-83, the author finds almost 4,000 laws, decrees, and administrative resolutions that create, maintain, or modify a foreign-trade regulation for the benefit of a single firm or industry. About half of them explicitly identify the petitioner - usually a firm or guild. Since the size of the Uruguayan economy changed over the period studied, the author scales the annual number of regulations by output or exports to measure the extent of rent-seeking trade policy. The author shows that the extent of rent-seeking trade policy increased with discretionary policies and under dictatorship. (In the period studied, there were two stages of democracy - until 1932 and from 1943-72 - and two stages of dictatorship.) He also shows that rent-seeking trade restrictions increased under import-substitution strategies and, more unexpectedly, under active export promotion. This suggests that discretionary power leads to wasteful distribution, whether it is used to support inward- or outward-oriented policies. Finally, the author analyzes the correlation between innovations in the trade policy indicator and innovations in the growth rates of output and exports, with a lag of up to 20 years. Surprisingly, he finds a positive correlation with output growth rates after two or three years. But the correlation becomes negative some years later, particularly in the case of exports. The short-run positive impact on growth rates, together with the surprisingly long time lag before the negative impact, may account for policymakers'receptiveness to demands for protection.Trade Policy,Achieving Shared Growth,TF054105-DONOR FUNDED OPERATION ADMINISTRATION FEE INCOME AND EXPENSE ACCOUNT,Economic Theory&Research,Environmental Economics&Policies
Double skew cyclic codes over Fq + vFq
In order to get a better code rate, this study focuses on the construction of double skew cyclic codes over the ring R = F-q + v(q) with v(2) = v , where q is a prime power. We investigate the generator polynomials, minimal spanning sets, generator matrices, and the dual codes over the ring R . As an implementation, the obtained results are illustrated with some suitable examples. Here, we introduce a construction for new generator matrices and thus achieve codes with improved parameters compared to those available in the existing literature. Finally, we tabulate our obtained codes over the ring R .Council of Scientific & Industrial Research (CSIR), Govt. of India [09/1023(0027)/2019-EMR-1]; Scientific and Technological Research Council of Turkey (TUBITAK) ARDEB 1002-A [123F286]In this research, the author Ashutosh Singh is thankful to the Council of Scientific & Industrial Research (CSIR), Govt. of India under File No. 09/1023(0027)/2019-EMR-1 and the author Tulay Yildirim is thankful to the Scientific and Technological Research Council of Turkey (TUBITAK) ARDEB 1002-A Grant No 123F286 for the financial support
Estimating Page Importance based on Page Accessing Frequency
With the vast growth of the Internet, many web pages are available online. Search engines use a component called as web crawlers for collecting these web pages from the web for storage and indexing. Many web pages are autonomous and are updated independent of the users..As the web pages are updated autonomously; users do not come to know of how often the sources change. An incremental crawler visits the web repeatedly after a specific interval of time for the updation of its collection. Users are benefited by knowing the page importance based upon the page accessing frequency. This paper finds out the page importance based on page accessing frequency and also architecture for the same is also proposed
Business process improvement using multi-objective optimisation
Business process redesign and improvement has become an increasingly attractive subject in the wider area of business process intelligence. Although there have been many attempts to establish a business process redesign framework, there is little work on the actual optimisation of business processes with given objectives. Furthermore, most of the attempts to optimise a business process are manual and do not involve a formal automated methodology. This paper proposes a process improvement approach for automated multi-objective optimisation of business processes. The proposed framework uses a generic business process model that is formally defined. The formal definition of business processes is necessary to ensure that the optimisation will take place in a clearly defined, repeatable and verifiable way. Multi-objectivity is expressed in terms of process cost and duration as two key objectives for any business process. The business process model is programmed and incorporated into a software optimisation platform where a selection of multi-objective optimisation algorithms can be applied to a business process design. This paper outlines a case study of business process design that is optimised by the state-of-the-art multi-objective optimisation algorithm NSGA2. The results indicate that, although business process optimisation is a highly constrained problem with fragmented search space, a number of alternative optimised business processes that meet the optimisation criteria can be produced. The paper also provides directions for future research in this area
Ashutosha Gowarikera lekcja patriotyzmu, czyli o roli kina indyjskiego w konstruowaniu tożsamości narodowej
LESSON IN PATRIOTISM BY ASHUTOSH GOWARIKER — THE ROLE OF INDIAN CINEMA IN CONSTRUCTING NATIONAL IDENTITY The paper is devoted to the nationalistic character of Indian film narratives given by Ashutosh Gowariker in his three movies: Lagaan, Swades and Jodhaa Akbar. Taking the cultural understanding of nationalism derived from the theories of Benedict Anderson, Eric Hobsbawn and Anthony Smith as a starting point, the author attempts to show how the director tries to build his narrations about India as an ‘imagined community.’ Since both cinema and the idea of ‘nation’ appeared in the subcontinent at approximately the same time, it is exceedingly essential to recognize the vital implications of their coexistence. Ashutosh Gowariker’s movies are one of the most interesting samples of Indian cinema’s endeavour to promote the idea of united India where people with different religious, ethnic and social backgrounds can live in peace and harmony. The nationalistic rhetoric manifests itself in the portrayal of the community’s solidarity against colonial exploitation, in the representation of both ideal Indian women and emigrant patriot, and finally in apotheosis of the great Muslim ruler whose tolerance serves as a role model for contemporary India and its struggle in facing the growth of religious fundamentalism.

Reconfigurable and heterogeneous architectures for efficient computing
The saturation of single-thread performance, along with the advent of the power wall, has resulted in the need for efficient use of area and power budgets. With the end of Dennard scaling, and the slow down of Moore's law, scaling from one process node to another no longer delivers gains in performance or power for general-purpose computing. Thus, there is an increase in the adoption of specialized hardware, tuned to the requirements of the application or domain. These accelerators promise high performance and energy efficiency. However, with the increasing complexity and resource requirements of applications and algorithms, there is also a need for more flexibility in these accelerator platforms. Along with high performance and energy efficiency, they must be able to cope with changes at an application and algorithmic level. In the face of these challenges, this dissertation explores the use of reconfiguration to balance flexibility, performance, and energy efficiency.
We begin by presenting three novel approaches that explore the use of reconfiguration in the three dominant computing devices -- CPUs, GPUs, and FPGAs. First, we consider general-purpose GPU (GPGPU) computing and highlight the inefficiencies in GPGPU, and identify opportunities to leverage reconfiguration to address these inefficiencies. Our solution is novel reconfigurable GPU architecture that can adapt to the needs of GPUs by dynamically allocating computational and memory resources among GPU cores (SMs). Second, we consider the limitations of dynamic partial reconfiguration (DPR) in modern FPGAs. We observe that while DPR is a potentially powerful technique, it is difficult to leverage. Thus, we propose an end-to-end methodology to leverage dynamic partial reconfiguration in FPGAs. The approach scales from edge to cloud devices, and presents an overlay architecture and an integer linear programming (ILP) based scheduler and mapper. We also demonstrate the ability to simultaneously map multiple applications to one FPGA, and explore different scheduling and sharing strategies. Third, we attempt to bridge the gap between the efficiency of reconfigurable computing and near-memory computing for general-purpose computing. Thus, we consider a modern multi-core CPU, and propose a novel architecture that uses SRAM arrays in the last level cache to create a reconfigurable computing fabric. Our approach is cheap, fast, energy-efficient, non-invasive, and flexible.
Finally, this dissertation concludes by considering the lessons learned from exploiting reconfiguration on CPUs, GPUs, and FPGAs, and asks how a modern reconfigurable computing device should be designed. With the explosion of data, large computational workloads, and increasing demands of efficiency, we propose a new memory-centric reconfigurable architecture, capable of fast dynamic reconfiguration and altering its compute to memory ratio and organization. We demonstrate significantly higher performance, density, and memory capacity than modern FPGAs.Submission published under a 24 month embargo labeled 'U of I Access', the embargo will last until 2023-05-01The student, Ashutosh Dhar, accepted the attached license on 2021-04-22 at 19:11.The student, Ashutosh Dhar, submitted this Dissertation for approval on 2021-04-22 at 19:22.This Dissertation was approved for publication on 2021-04-23 at 08:48.DSpace SAF Submission Ingestion Package generated from Vireo submission #16518 on 2021-09-16 at 17:05:00Made available in DSpace on 2021-09-17T02:34:45Z (GMT).

The Evolution of Artificial Intelligence Origin : impact on workforce and future implications
Artificial intelligence (AI) has rapidly evolved from theoretical models to real-world applications that impact every sector of the global economy. While AI promises increased efficiency, productivity, and innovation, it also brings significant disruption to traditional labor markets. The transition from industrial automation to AI-driven decision-making has accelerated job displacement across both blue-collar and white-collar industries. This chapter explores the historical context of job displacement due to AI, the sectors most at risk, and potential strategies for mitigating the economic and social consequences of this transformation
