Nadzieje na powrót turystyki w Indiach po pandemii
No full textIn post-pandemic India the recovery in tourism has become known as ‘revenge’ meaning revenge on the disease. It is tourism due to the desperation to travel, especially in the current scenario in which those who have been confined to their homes have grown tired of being trapped there. The restless mood caused by the ongoing pandemic reached its peak and it is possible that this will eventually help in bringing back a rapid return to tourism. To analyze the travel intentions of potential tourists after the current pandemic ends, an attempt has been made to make an analysis of tourism in India to find out how Covid-19 is impacting on people’s lives and how willing they are to participate in tourism again.W Indiach po złagodzeniu długotrwałych obostrzeń pandemicznych zaobserwowano zjawisko odradzania się podróżowania, znane pod nazwą turystyki zemsty (ang. revange tourism), traktowanej jako szczególny odwet na chorobie. Obserwowana dzisiaj potrzeba podróżowania wynika z desperackiej chęci odreagowania poczucia zmęczenia i uwięzienia we własnych domach. Niepokój wywołany pandemią osiągnął apogeum i możliwe jest, że przyczyni się do wznowienia ruchu turystycznego. W celu przeanalizowania intencji potencjalnych podróżnych podjęto próbę zbadania branży turystycznej w Indiach pod kątem wpływu COVID-19 na życie ludzi i ich chęci ponownego udziału w turystyce

Functional relations involving generalized H-function
Get PDFA number of papers have appeared in literature in which certain functional relations associated with hypergeometric functions and Digamma function ψ(z) are derived. In order to unify and extend the existing results due to Kalla [7]. Kalla and Ross [9], Al-Saqabi and Kalla [1], Nishimoto and Saxena [12], Srivastava and Nishimoto [17] and Pandey and Srivastava [14] etc., the author establishes two functional relations between ψ(z) and generalized H -function due to Inayat-Hussain [6]. The results obtained are of general character and provide extension and unification of functional relations of various hypergeometric functions available in literature. Existence conditionsand computable representation of the H -function are also investigated.<br /
The evolving politics of labor standards in Bangladesh: taking stock and looking forward
No full textThis chapter provides a brief history of three or more decades of national and international efforts to improve labor standards for the workers in the garment industry. It concludes by looking forward to what could be done in the future. The author draws on her own research in this field to structure the wider literature on this topic. This chapter argues that any account of achievements and failures in relation to these efforts has to be embedded in the wider context in which the Bangladesh industry emerged and grew because this helps us to understand why its working conditions continue to fall short of international conventions and national regulations. While it faces the difficulties faced by any underdeveloped country with a limited history of industrialization and an industrial working class, Bangladesh has featured particularly prominently in international efforts to promote labour standards in global value chains in the garment sector. It can therefore provide an important case study of the challenges encountered by these efforts when the apparent protectionism of powerful global actors encounter the apparent intransigence of locally powerful actors
Clustering Under Perturbation Stability in Near-Linear Time
Get PDFWe consider the problem of center-based clustering in low-dimensional Euclidean spaces under the perturbation stability assumption. An instance is α-stable if the underlying optimal clustering continues to remain optimal even when all pairwise distances are arbitrarily perturbed by a factor of at most α. Our main contribution is in presenting efficient exact algorithms for α-stable clustering instances whose running times depend near-linearly on the size of the data set when α ≥ 2 + √3. For k-center and k-means problems, our algorithms also achieve polynomial dependence on the number of clusters, k, when α ≥ 2 + √3 + ε for any constant ε > 0 in any fixed dimension. For k-median, our algorithms have polynomial dependence on k for α > 5 in any fixed dimension; and for α ≥ 2 + √3 in two dimensions. Our algorithms are simple, and only require applying techniques such as local search or dynamic programming to a suitably modified metric space, combined with careful choice of data structures
Atomic and Near-atomic Scale Additive Manufacturing: Past, Present, and Future Outlook
No full textThe next stage of micro manufacturing is nano and atomic scale manufacturing. A state-of-the-art approach to manufacturing, atomic and near-atomic scale additive manufacturing (ACSM) seeks to manipulate materials at the atomic or near-atomic level to produce next-generation goods with previously unheard-of precision. Currently, facility for manufacturing and machining at nano and atomic scale is in developing stage, the technique used in the atomic force microscope giving a positive hope to develop a facility for machining a material or deposited a material. The historical evolution from craft-based manufacturing (millimetre precision) and precision-controllable manufacturing (micrometre to nanometre accuracy) to atomic-scale precision is built upon by this field, which is frequently referred to as Manufacturing III. An outline of ACSM is provided here, with an emphasis on current advancements, methods, uses, and difficulties, especially about additive manufacturing. The ACSM is a next stage of industrial revolution
Challenges and Opportunities in Additive Manufacturing in Defence Applications
No full textIn recent years, Additive Manufacturing (AM) has gained significant attention due to its versatility and low-waste production cycle. Additive manufacturing fabricates complex, intricated structures and miniaturized shapes with high dimensional accuracy, tailored properties, multiple materials in a single part, and colour aesthetics. many solid-state and liquid-state AM techniques are available to achieve specific mechanical properties while simultaneously providing thermal and structural stability. Powder bed fusion (PBF) and direct energy deposition (DED) have the potential to make components for the defence and industrial sectors. The part production speed with AM techniques limits the application in mass production. The process involved in this technique is limited to polymers and non-metals for processing, and defects due to the liquid-solid interface need a lot of research to be done. The proposed chapter describes the role of AM in the defence sector and the challenges involved
Architectural & circuit level techniques to improve energy efficiency of high speed serial links
Get PDFHigh performance computing and communication are two key aspects of all information processing systems. With aggressive scaling of silicon technology enabling integration of a large number of transistors in a small area, managing power and thermal reliability has become very challenging. While lowering the power needed for performing computation has been the prime focus for decades, energy consumed for data transfer has recently become a major bottleneck especially in high performance applications. The focus of this thesis is on improving energy efficiency of communication links by exploring design techniques at both the architectural and circuit levels.
In the first part of this work, we propose a time-based equalization scheme to implement transmit de-emphasis in voltage-mode output drivers. Using two-level pulse-width modulation, it overcomes the tradeoff between impedance matching, output swing, and de-emphasis resolution in conventional voltage-mode drivers. A prototype PWM-based 5Gb/s voltage-mode transmitter was implemented in a 90nm CMOS process and characterized across different channels and output swings to demonstrate the effectiveness of proposed techniques. The horizontal/vertical eye openings (BER=) at the ends of 60inch and 96inch stripline channels are 78mV/0.6UI and 8mV/0.3UI, respectively. This transmitter achieves an energy efficiency of 3.1mW/Gb/s while compensating for 16-28dB channel loss, which compares favorably with the state-of-the-art.
In the second part, techniques to improve energy efficiency of a complete transceiver are presented. The transmitter employs a novel partially segmented voltage-mode output driver to lower power consumption in pre-drivers during 2-tap FIR equalization. The receiver implements a low power half-rate clock and data recovery with the proposed ring PLL based multi-phase sampling clock generation in CDR loop and charge-based sampling and deserialization. These techniques are verified using the measured results obtained from a 14Gb/s transceiver prototype. Transmitter achieves an energy efficiency of 0.89mW/Gb/s while securing a 0.36UI sampling time margin with at the end of the channel with 11dB loss at Nyquist frequency. The receiver recovers sampling clock with 1.8 long term absolute jitter while recovering 14Gb/s data at . The receiver achieves an energy efficiency of 1.69mW/Gb/s. Transmitter and receiver share an LC PLL, which achieves 0.605 integrated jitter at 7GHz output with an energy efficiency of 0.5mW/GHz. The transceiver as a whole achieves an energy efficiency of 2.8mW/Gb/s.Submission published under a 24 month embargo labeled 'Closed Access', the embargo will last until 2017-12-01The student, Saurabh Saxena, accepted the attached license on 2015-11-16 at 16:11.The student, Saurabh Saxena, submitted this Dissertation for approval on 2015-11-16 at 16:37.This Dissertation was approved for publication on 2015-11-18 at 17:00.DSpace SAF Submission Ingestion Package generated from Vireo submission #8792 on 2016-03-02 at 14:13:10Made available in DSpace on 2016-03-02T21:06:32Z (GMT).
