Natural language descriptions for video streams (2012)

This thesis is concerned with the automatic generation of natural language descriptions\nthat can be used for video indexing, retrieval and summarization applications.\nIt is a step ahead of keyword based tagging as it captures relations between keywords\nassociated with videos, thus clarifying the context between them. Initially,\nwe prepare hand annotations consisting of descriptions for video segments crafted\nfrom a TREC Video dataset. Analysis of this data presents insights into humans\ninterests on video contents. For machine generated descriptions, conventional image\nprocessing techniques are applied to extract high level features (HLFs) from\nindividual video frames. Natural language description is then produced based on\nthese HLFs. Although feature extraction processes are erroneous at various levels,\napproaches are explored to put them together for producing coherent descriptions.\nFor scalability purpose, application of framework to several different video genres\nis also discussed. For complete video sequences, a scheme to generate coherent and\ncompact descriptions for video streams is presented which makes use of spatial and\ntemporal relations between HLFs and individual frames respectively. Calculating\noverlap between machine generated and human annotated descriptions concludes\nthat machine generated descriptions capture context information and are in accordance\nwith human’s watching capabilities. Further, a task based evaluation shows\nimprovement in video identification task as compared to keywords alone. Finally,\napplication of generated natural language descriptions, for video scene classification\nis discussed.
Ethical issues in web data mining (2004)

Web mining refers to the whole of data miningand related techniques that are used toautomatically discover and extract informationfrom web documents and services. When used in abusiness context and applied to some type ofpersonal data, it helps companies to builddetailed customer profiles, and gain marketingintelligence. Web mining does, however, pose athreat to some important ethical values likeprivacy and individuality. Web mining makes itdifficult for an individual to autonomouslycontrol the unveiling and dissemination of dataabout his/her private life. To study thesethreats, we distinguish between `content andstructure mining' and `usage mining.' Webcontent and structure mining is a cause forconcern when data published on the web in acertain context is mined and combined withother data for use in a totally differentcontext. Web usage mining raises privacyconcerns when web users are traced, and theiractions are analysed without their knowledge.Furthermore, both types of web mining are oftenused to create customer files with a strongtendency of judging and treating people on thebasis of group characteristics instead of ontheir own individual characteristics and merits(referred to as de-individualisation). Althoughthere are a variety of solutions toprivacy-problems, none of these solutionsoffers sufficient protection. Only a combinedsolution package consisting of solutions at anindividual as well as a collective level cancontribute to release some of the tensionbetween the advantages and the disadvantages ofweb mining. The values of privacy andindividuality should be respected and protectedto make sure that people are judged and treatedfairly. People should be aware of theseriousness of the dangers and continuouslydiscuss these ethical issues. This should be ajoint responsibility shared by web miners (bothadopters and developers), web users, andgovernments.

Penetration testing: Concepts, attack methods, and defense strategies (2016)

Penetration testing helps to secure networks, and highlights the security issues. In this paper investigate different aspects of penetration testing including tools, attack methodologies, and defense strategies. More specifically, we performed different penetration tests using a private networks, devices, and virtualized systems and tools. We predominately used tools within the Kali Linux suite. The attacks we performed included: smartphone penetration testing, hacking phones Bluetooth, traffic sniffing, hacking WPA Protected Wifi, Man-in-the-Middle attack, spying (accessing a PC microphone), hacking phones Bluetooth, and hacking remote PC via IP and open ports using advanced port scanner. The results are then summarized and discussed. The paper also outlined the detailed steps and methods while conducting these attacks.
Plasma diagnostics in industry (2000)

Plasma processing forms an invaluable part of semiconductor device manufacturing. For the most part, commercial tools have relied on an empirical process for their evolution and relied exclusively on plasma characterization only at the development stage. As this industry advances there is the need to provide non-invasive plasma characterization and diagnostics on the processing equipment, in order to provide more control over the plasma properties. We outline some of the typical configurations used in the industry and describe two of the measurement techniques we have developed for the characterization of these industrial plasma sources.
Bibliography and references (2010)

Professional services marketing is a relatively new form of marketing that has been recogonized only since the late 1980s. Most of the attempts to write about marketing for professional services have been a regurgitation of the traditional marketing approach that has evolved since the 1960s and have concentrated on minor differences and adjustments. In many ways, what is needed is a fresh approach which takes into account the complex political, social, economic, legislative and cultural backdrop and provides a way for design professionals, such as architects and engineers, to look to the future. This book does just that.
Discrete logarithms and local units (1993)

Abstract Let K be a number field and (9K its ring of integers. Let l be a prime number and e a positive integer. We give a method to construct leth powers in (9K using smooth algebraic integers. This method makes use of approximations of the l-adic logarithm to identify leth powers. One version we give is successful if the class number of K is not divisible by l and if the units in CK which are congruent to 1 modulo le+1 are leth powers. A second version only depends on Leopoldt’s conjecture. We use the technique of constructing leth powers to find discrete logarithms in a finite field of prime order. Our method for computing discrete logarithms is closely modelled after Gordon’s adaptation of the number field sieve to this problem. We conjecture th at the expected running time of our algorithm is Lp[1/3; (64/9)1/3 + o(1)] for p-&gt; oo, where Lp[s; c] = exp (c (log q)s (log log q)1-8). This is the same running time as is conjectured for the number field sieve factoring algorithm.
Intercalators promote the binding of RecA protein to double-stranded DNA. (1990)

Ethidium bromide, acridine orange, 4'-(9-acridinylamino)methanesulfon-o-anisidide (o-AMSA), and m-AMSA induce the rapid binding of RecA protein to double-stranded (ds) DNA. The filaments formed appear to retain the drug and are 12.8 nm in diameter with an 8.0-nm pitch. Two classes of drugs have been distinguished: (i) those that bind to RecA protein and induce assembly at low relative concentrations (e.g., ethidium bromide) and (ii) those that do not appear to interact directly with RecA protein and must be present at relatively high drug concentrations to stimulate assembly (e.g., m-AMSA). Ethidium bromide, acridine orange, and quinacrine inhibit RecA protein binding to single-stranded DNA. Addition of ATP to the drug-induced filaments causes the protein to rapidly dissociate from dsDNA, and protein binding to dsDNA diminishes upon extended exposure to room light. We suggest that the structure of the drug-induced filaments may be more typical of the complex that initiates RecA protein assembly along DNA rather than the product of extensive polymerization as induced by adenosine 5'-[gamma-thio]triphosphate.
A history of cognitive rehabilitation (2005)

Abstract This chapter provides a brief history of cognitive rehabilitation. It reviews how brain injuries sustained in war have provided great stimulus both to the theoretical foundations of neuropsychology, and to some of the early formulations of the process of rehabilitation. Historical accounts are always shaded by the perspective of the historian who recounts past events: thus multiple perspectives are needed when attempting to obtain an accurate history of cognitive rehabilitation.
TBGA package technology (1994)

TBGA or Tape Ball Grid Array is a ball grid array package which utilizes solder bumps to connect the TAB tape to the printed circuit card or board. The array of outer lead bond (OLB) joints is typically on a 50 mil grid. This technology differs from conventional TAB peripheral OLB in that the package can be "picked and placed" using conventional card assembly equipment and processes at very high assembly yields. If thermal enhancement is required, a heatsink can be attached to the die. The technology can be applied to both single and double level metal tape; and can utilize various inner lead bonding (ILB) techniques, i.e., peripheral thermocompression, thermosonic, or wirebonding, and area array solder reflow. This paper describes the package technology, applications, and attributes.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
Chaos in Random Neural Networks (1988)

A continuous-time dynamic model of a network of $N$ nonlinear elements interacting via random asymmetric couplings is studied. A self-consistent mean-field theory, exact in the $N\ensuremath{\rightarrow}\ensuremath{\infty}$ limit, predicts a transition from a stationary phase to a chaotic phase occurring at a critical value of the gain parameter. The autocorrelations of the chaotic flow as well as the maximal Lyapunov exponent are calculated.
Treatment of Altered Body Composition in HIV-Associated Lipodystrophy: Comparison of Rosiglitazone, Pravastatin, and Recombinant Human Growth Hormone (2008)

Prolonged rosiglitazone treatment slowly improves lipoatrophy. rhGH rapidly and selectively reduces visceral fat, although effects are short-lived; co-administered rosiglitazone abrogates rhGH-related insulin resistance.
Oxindoles and Their Pharmaceutical Significance- An Overview (2011)

Oxindoles are credited to have a wide range of applications and are reported to exhibit an extensive range of biological effects which include the antiviral, antifungal, antibacterial, antiproliferative, anticancer, anti-inflammatory antihypertensive and the anticonvulsant activities. The chemistry of oxindoles is very interesting and the biological activity of the oxindoles and their derivatives has made them very important in synthetic organic and medicinal chemistry. This review provides insight into various applications of oxindoles and their derivatives to date.
Road Extraction by Deep Residual U-Net (2018)

Road extraction from aerial images has been a hot research topic in the field of remote sensing image analysis. In this letter, a semantic segmentation neural network, which combines the strengths of residual learning and U-Net, is proposed for road area extraction. The network is built with residual units and has similar architecture to that of U-Net. The benefits of this model are twofold: first, residual units ease training of deep networks. Second, the rich skip connections within the network could facilitate information propagation, allowing us to design networks with fewer parameters, however, better performance. We test our network on a public road data set and compare it with U-Net and other two state-of-the-art deep-learning-based road extraction methods. The proposed approach outperforms all the comparing methods, which demonstrates its superiority over recently developed state of the arts.
Recovery oriented programming (2005)

Computerized management of critical systems makes the issues of correctness and faultless flow of long-lived and continuously-running programs extremely important e.g., [6, 7]. Complex systems cannot be fully verified because their verification may require an unreasonable amount of time and space. The software industry tests software products extensively in order to eliminate bugs as much as possible. Normally, software is tested by executing a set of large, but length-bounded and non-exhaustive scenarios starting from a predefined initial state while each scenario is defined by a set of input/output sequences. Undesired and unplanned behavior (bug) may occur due to scenarios that were not tested prior to the software release. Software malfunctions may cause damage that can outweigh the software cost. Keeping all this in mind, a consumer of a critical system would like to have a warranty that such a system will operate properly.
High‐throughput screening for the development of a monoclonal antibody affinity precipitation step using ELP‐z stimuli responsive biopolymers (2013)

This study provides a detailed investigation into the performance of a stimuli responsive ELP-Z based process for monoclonal antibody (mAb) affinity precipitation. A multidimensional high-throughput screening (HTS) protocol was developed and employed to investigate the effects of a variety of operating conditions on mAb yield and aggregation during the process. Precipitation efficiency of ELP-Z in the absence of mAb was first determined as a function of temperature and sodium sulfate concentration and conditions producing high yields were identified. HTS was then employed to determine appropriate conditions for the initial capture and co-precipitation of mAbs at high yields using ELP-Z. mAb elution from ELP-Z was then examined using HTS and the mAb yields and aggregate content of the overall process were determined. It was observed that mAb aggregation was sensitive primarily to the elution conditions and that this behavior was antibody specific and a strong function of operating temperature and elution pH. Importantly, for both mAbs examined in this study, the results indicated that room temperature operation and appropriate elution pH could be readily employed to produce both high mAb yields and low aggregate content using this approach. This study demonstrates the ability of ELP-Z based affinity precipitation for mAb purification and shows that HTS can be successfully employed to rapidly develop a robust and high yield process.
High-Pressure Diels−Alder Cycloadditions between Benzylideneacetones and 1,3-Butadienes: Application to the Synthesis of (<i>R,R</i>)-(−)- and (<i>S,S</i>)-(+)-Δ<sup>8</sup>-Tetrahydrocannabinol (2010)

High-pressure Diels-Alder reactions of various alkoxy/alkyl-substituted benzylideneacetones with methyl-1,3-butadienes are reported. Activation by high pressure (8-11 kbar) in combination with the mild Lewis acid HfCl(4).2THF allows these reactions to efficiently and regioselectively produce a series of ortho-substituted cyclohexenyl-benzene cycloadducts, that are useful precursors for the expeditious construction of the privileged 6,6-dimethyltetrahydro-6H-benzo[c]chromene skeleton. Application to the synthesis of Delta(8)-trans-THC in both enantiomeric pure forms is based on the successful resolution of selected cycloadduct by the SAMP-hydrazone method.

Effect of Chitosan and Mordant Treatments on the Color Change of Cotton and Nylon Fabrics Dyed using Japanese Pagoda Tree (2006)

In this study, the effects of chitosan pre-treatment on the mordanting effect and dyeability were investigated in the dyeing using Japanese pagoda tree. The chitosan treatment effects were evaluated mainly focused on the colors after dyeing of cotton and nylon fabrics which were treated with acidic aqueous solution of chitosan. In the case of chitosan untreated fabrics, the mordanting effects on the cotton and nylon were insignificant and the dyeability was very low. Regardless of the mordant types(Al, Sn, and Fe), the dyed fabrics exhibited almost identical yellowish colors. In the case of chitosan treated fabrics, dark colors were obtained compared to the case of chitosan untreated and values were increased significantly. In cotton fabrics, the most excellent result was obtained under the condition of unmordanted and chitosan treated fabrics. This verifies the fact that routin coloring matters establish direct linkages with the chitosan components, which exhibit cationic nature, easily. In nylon fabrics, the effects of mordanting treatment and chitosan treatment are so insignificant that the routin coloring matters are presumed to establish direct dyeing with the nylon molecular chains.
A low noise amplifier with application to noise thermometry between 300 and 4 K (1974)

A low noise FET amplifier has been constructed and applied to noise thermometry. The amplifier noise is less than 1 nV/(Hz)1/2 above 5 kHz. Temperatures between 300 and 4 K have been measured to better than 1% with a time constant of 5 sec. A description of the complete noise thermometer system is given.
COMPOSITIONAL VARIATIONS IN AGED AND HEATED PISTACIA RESIN FOUND IN LATE BRONZE AGE CANAANITE AMPHORAE AND BOWLS FROM AMARNA, EGYPT* (2003)

This study examines resinous deposits from the interior surfaces of sherds of imported Canaanite amphorae and locally produced bowls from the 18th Dynasty site of Tell el‐Amarna, Egypt. Archaeological evidence indicates that the Canaanite amphorae were used for resin transport, whilst the bowls are associated with burning resin as incense. A number of characteristic triterpenoids identify all the resinous deposits from both vessel types as Pistacia spp. No other resins were observed and there was no evidence of mixing with oils or fats. The composition of the archaeological resins is more complex than that of modern pistacia resin, due to degradation and generation of new components. Experimental heating alters the relative abundance of the triterpenoid composition of modern pistacia resin. One component, the triterpenoid 28‐norolean‐17‐en‐3‐one, is produced by such heating; however, an increase in its relative abundance in ancient samples is not matched by the archaeological evidence for heating. It is therefore not possible to use this component reliably to identify heated resin. However, additional unidentified components with a mass spectral base peak at m/z 453 have been associated with seven (out of 10) bowls and are not observed in resins associated with Canaanite amphorae. It is proposed that these components are more reliable molecular indicators of heating.
Power-Sharing with Electric Propulsion and Secondary Batteries (1971)

An in-house study has revealed that most AF synchronous equatorial satellites have an appreciable fraction of power on the spacecraft which is not being used continuously. The study reveals that this excess power may be used to operate electric thrusters for stationkeeping functions, on an appropriate duty cycle. By selecting the proper secondary battery charge rate, commensurate with battery capacity and reliability, the electric thruster performance may be optimized to maximize satellite payload capabilities. Percent payload improvement from a few percent to 25% when compared to a non-power-sharing ion engine, and from 5 to 75% compared to a power-sharing colloid engine may be realized.
Carbon dioxide absorption into promoted carbonate solutions (1988)

Abstract CO 2 absorption rates into diethanolamine (DEA)‐promoted carbonate solutions were measured over a wide range of carbonate conversions and temperatures. Analysis of the data showed that the CO 2 ‐DEA reaction rate was controlled by the rate of formation of zwitterion intermediate for carbonate conversions below 30%, and was controlled by the rate of abstraction of proton from the zwitterion intermediate for carbonate conversions greater than 30%. Hydroxyl ion, free amine, and carbonate ion were identified to act as bases to abstract the proton from the zwitterion. The modeling of the CO 2 absorption rates and the effects of carbonate conversion and amine concentration on the CO 2 ‐DEA reaction kinetics were investigated.
Agent based intrusion detection and response system for wireless LANs (2004)

Wireless LAN technology, despite the numerous advantages it has over competing technologies, has not seen widespread deployment. A primary reason for markets not adopting this technology is its failure to provide adequate security. Data that is sent over wireless links can be compromised with utmost ease. In this project, we propose a distributed agent based intrusion detection and response system for wireless LANs that can detect unauthorized wireless elements like access points, wireless clients that are in promiscuous mode etc. The system reacts to intrusions by either notifying the concerned personnel, in case of rogue access points and promiscuous nodes, or by blocking unauthorized users from accessing the network resources.
