Establishment of Secure Communication in Wireless Sensor Networks (2012)

Wireless sensor networks (WSNs) consists of small nodes with constrained capabilities to sense, collect, and disseminate information in many types of applications. Wireless sensor networks (WSN) have attracted significant interests from the research community in a wide range of applications such as target tracking, environment monitoring, military sensing, distributed measurement of seismic activity, and so on.As sensor networks become wide-spread, security issues become a central concern. In this paper, we identify the Security requirements of key management in WSN. The secure management of the keys is one of the most critical elements when integrating cryptographic functions into a system. An outline of hybrid cryptography, one way hash and Key infection schemes are discussed in this paper. Along the way we analyze the advantages and disadvantages of current secure schemes. Finally, we aim to provide the different techniques of efficient key management operations for secure communications in WSN.
Airborne Spacing: Managed vs. Selected Speed Mode on the Flight Deck (2006)

This paper reports on an experiment conducted with airline pilots on a fixed-based cockpit simulator. The objective was to assess the use of a speed managed mode for airborne spacing, compared to a speed selected mode. The availability of a speed managed mode reinforced the pilot acceptability. All pilots found airborne spacing feasible and compatible with their usual flying task, from cruise until automatic disengagement at 2000 feet. The speed managed mode was found as the most appropriate during the initial descent but the speed selected mode was preferred by some pilots during final approach. The spacing was well maintained below the 5 seconds tolerance margins with an average of –0.1 second and a 95% containment within ±2.5 seconds. The cost induced is in the order of 60 knots additional speed changes for the complete descent phase, with a maximum but also a minimum cost when using the speed selected mode. This raises the issue of trade-off between required performance (spacing accuracy) and cost induced (speed changes).
Bayesian learning of speech duration models (2003)

This paper presents the Bayesian speech duration modeling and learning for hidden Markov model (HMM) based speech recognition. We focus on the sequential learning of HMM state duration using quasi-Bayes (QB) estimate. The adapted duration models are robust to nonstationary speaking rates and noise conditions. In this study, the Gaussian, Poisson, and gamma distributions are investigated to characterize the duration models. The maximum a posteriori (MAP) estimate of gamma duration model is developed. To exploit the sequential learning, we adopt the Poisson duration model incorporated with gamma prior density, which belongs to the conjugate prior family. When the adaptation data are sequentially observed, the gamma posterior density is produced with twofold advantages. One is to determine the optimal QB duration parameter, which can be merged in HMMs for speech recognition. The other one is to build the updating mechanism of gamma prior statistics for sequential learning. EM algorithm is applied to fulfill QB parameter estimation. The adaptation of overall HMM parameters can be performed simultaneously. In the experiments, the proposed adaptive duration model improves the speech recognition performance of Mandarin broadcast news and noisy connected digits. The batch and sequential learning are respectively investigated for MAP and QB duration models.
Paper Material Considerations for System Printers (1984)

Laser printing of continuous forms by means of electrophotographic imaging requires that the paper on which the printing is carried out show good handling characteristics at fast machine speeds and be compatible with toner transfer and fixing. Toner transfer requires suitable electrical paper characteristics, similar to those of xerographic cut sheets intended for use in electrophotographic cut-sheet copiers and printers. Hot-pressure fusing in the IBM 3800 printing subsystem has been shown to require adequate paper-fiber wettability by the hot molten toner. Therefore, characteristics of paper chemistry, and in particular paper sizing, are essential in creating good image fixing (fusing). In addition, the temperature and pressure in the fusing assembly affect the thermal and dimensional stability of the paper. For the 3800, this necessitated modifications in roll design within the fusing station in order to ensure satisfactory paper handling.
Effect of Dietary Fat on Tissue Fat and Plasma Cholesterol Level in Broilers (1962)

THE EFFECT of dietary fat on the fat content of the chicken carcass has been studied by several investigators. Baldini and Rosenberg (1957) reported that an increase in the fat content of the diet without raising the caloric content did not increase deposition of body fat. Donaldson et al. (1956) found that wider Calorie/protein ratios increased the carcass fat. Leong et al. (1959) reported that visceral fat deposition was affected more by source and amount of energy than by Calorie/protein ratio. While these studies have shown that increasing the energy content of the diet will increase total carcass fat, they do not give information about the distribution of the fat in muscle tissue. A comprehensive study of the effect of fattening diets on the tissue fat content of 8-to 20-week-old cockerels was made by Harshaw (1938). More recently, McNally (1954) reported that the fat content of edible meat of 12-week-old …
Dispersive manipulation of paired superconducting qubits (2004)

We combine the ideas of qubit encoding and dispersive dynamics to enable robust and easy quantum-information processing on paired superconducting charge boxes sharing a common bias lead. We establish a decoherence free subspace on these and introduce universal gates by dispersive interaction with a $\mathrm{LC}$ resonator and inductive couplings between the encoded qubits. These gates preserve the code space and only require the established local symmetry and the control of the voltage bias. The principle of dispersive manipulation of encoded qubits is general and beneficial to other physical systems.
Towards Security Two-part Authenticated Key Agreement Protocols. (2005)

We first present a new security 2-AK protocol, which is more secure and more efficient than previously proposed ones. Meanwhile, we point that Xie’s ID-2-AK protocol modified from McCullagh-Barreto in CT-RSA 2005 doesn’t provide protection against KCI attack likewise, and finally utilize the modular arithmetic, first proposed in MQV and also used in Kim, to get a modified new ID-2-AK protocol. On second thoughts, we give another ID-2-AK protocol utilizing the operation of addition in finite field like our forenamed 2-AK protocol. The two ID-2-AK protocols are in possession of all the desired security attributes. We also compare our new protocols with others in terms of computational cost and security properties.
Landau-Lifshitz-Bloch equation for ferrimagnetic materials (2012)

We derive the Landau-Lifshitz-Bloch (LLB) equation for a two-component magnetic system valid up to the Curie temperature. As an example, we consider disordered GdFeCo ferrimagnet where the ultrafast optically induced magnetization switching under the action of heat alone has been recently reported. The two-component LLB equation contains the longitudinal relaxation terms responding to the exchange fields from the proper and the neighboring sublattices. We show that the sign of the longitudinal relaxation rate at high temperatures can change depending on the dynamical magnetization value and a dynamical polarization of one material by another can occur. We discuss the differences between the LLB and the Baryakhtar equations, recently used to explain the ultrafast switching in ferrimagnets. The two-component LLB equation forms the basis for the large-scale micromagnetic modeling of nanostructures at high temperatures and ultrashort time scales.
A neural network approach to real-time motion planning and control of robot manipulators (2003)

Real-time motion planning and control of multi-joint robot manipulators are studied using neural networks. The proposed neural network approach consists of two modules: one for real-time collision-free motion planning, the other for real-time fine control of the robot manipulators. The motion planning module is a biologically inspired, parallel connected, topologically organised neural network, where each neuron is characterised by a shunting equation, whose state space is the robot configuration joint space. This module is capable of planning a real-time optimal path for robot manipulators through the dynamic activity landscape of the neural network. The motion control module involves of a feedforward neural network together with a traditional PD feedback loop. It is capable of achieving real-time fine motion control of robot manipulators under significant uncertainties and without any prior knowledge of the robot dynamics. This module can quickly compensate sudden changes in the robot dynamics. The real-time fine control of robot manipulators is achieved through the online learning of the neural network. Both the motion planning and motion control modules are computationally efficient, and their global stabilities are proved using Lyapunov stability theory.
Analysis of the rat clusterin gene promoter and cyclic AMP-regulated mRNA stability in testicular cells (1996)

Clusterin, also known as SGP-2 or TRPM-2, is expressed in the male reproductive tissues at different levels. The genomic structure of the rat clusterin gene was recently reported by our laboratory and others. In this study, we have determined the promoter responsible for the basal expression of the rat clusterin gene in testicular cells by analyzing the transient expression of the bacterial chloramphenicol acetyl transferase (CAT) reporter gene in MA-10 cells driven by different segments of the 5'-flanking region and the first intron of the clusterin gene. The region required for maximal basal expression was identified at -266 to +54. Addition of DNA fragments of the rat clusterin gene from -1298 to -266 bp, or from +54 to +1153 to (-266/+54)CAT resulted in a 87% decrease in CAT activity, suggesting the presence of inhibitory DNA elements in both the 5'-flanking region and the first intron. When DNA fragment in the first intron, +1153 to +2874, was included, CAT activity in the (-266/+2874)CAT construct increased to 70% of the clusterin promoter (-266/+54)CAT, indicating that stimulatory DNA elements may be present in this region of the first intron. Treatment of MA-10 cells with cyclic AMP (cAMP) neither decreased CAT activity driven by any of the clusterin/CAT chimeric plasmids examined in transient transfection studies, nor reduced the synthesis of nuclear clusterin RNA in nuclear run-on assays, indicating that the reduction of clusterin mRNA levels by cAMP previously reported in our laboratory is not exerted at the transcriptional level. Furthermore, addition of transcriptional or translational inhibitors (actinomycin D and cycloheximide respectively) abolished the cAMP effect observed in MA-10 cells. In summary, we have demonstrated that the basal transcription of the rat clusterin gene in testicular cells is under the control of both positive and negative regulatory sequences at the 5'-flanking region as well as in the first intron. The reduction of clusterin mRNA after exposure of MA-10 cells to cAMP is not due to a decrease in its transcriptional activity, but rather to an increase in the degradation of this mRNA through synthesis of a destabilizing protein(s) and its mRNA.

Adding a microcontroller to an average PC power supply transforms it into a flexible, intelligent device that can be configured and that is suitable to keep car batteries always ready to use. Using a high-performance microcontroller provides the product with wireless communication capabilities so it becomes a new network device that can be accessed through the Internet. This project allows students to improve their knowledge in several fields: power electronics, battery charging and conditioning, advanced microcontrollers, embedded Linux, and wireless communications.
Adaptation of Block Chain Technology in manufacturing sector (2020)

Block chain technology, hailed as the new internet is a revolutionary concept that can ensure transparent transactions through data authenticity and integrity with wide coverage area ranging from business to healthcare to real estate and designed to operate in the framework of an interlinked network or cluster of computing systems. Taking the example of the manufacturing sector, there are several transactions including sales, purchase and other expenditures that are to be accounted and there is a need for several ledgers maintained such as cash books, sales and purchase accounts which can be replaced by a single distributed ledger in public domain in chronological order. Also, in project activities there are capital costs that include infrastructure as well as technology costs, operational expenses and several direct and indirect expenses. Block chain technology can play a vital role in these transactions and can have wide scope in the area of logistics particularly in supply order processing including smart contracting, supply chain management, energy management, assets transfer, part processing, design, patent handling, electronic commerce, digital strategies and in ERP methodologies. While the idea of such a system is proposed to be the most preferred mode of transactions with data security and traceability and decentralization there are several challenges that need to be addressed before its implementation in totality. This paper intends to bring out the requirements analysis through expectations of the manufacturing sector by which it can possibly benefit from the integration of blockchain technology into the system.
A Novel Synthesis of Enantiomerically Pure 5,5,5,5‘,5‘,5‘-Hexafluoroleucine (2001)

[reaction in text] A novel, short, and efficient synthesis of (S)-5,5,5,5',5',5'-hexafluoroleucine (6) in greater than 99% ee starting from the protected oxazolidine aldehyde 1 is described. The enantiomeric excess of the product was calculated from an NMR analysis of a dipeptide formed by reaction with a protected L-serine derivative. Furthermore, a racemic sample of N-acylated hexafluoroleucine was enzymatically resolved by treatment with porcine kidney acylase I and was found to have the same optical rotation as a synthetic sample of 6.

Photographic Properties of Oxygen Heterocyclic Developing Agents (1967)

Several derivatives of 7, 8-dihydroxybenzopyrylium chloride and of 7, 8-dihydroxycoumarin (daphne- tin) were synthesized and investigated as developing agents. They function best in the pH range 10-11, and possess similar photographic properties to pyrogallol, but show better keeping properties in solution. The best compounds are daphnetin, its 3-methyl derivative and its 3, 4-dimethyl derivative. These give higher speed for the same contrast than do catechol or metol.
[Pillars of therapy of chronic obstructive bronchitis]. (1989)

While bronchial asthma is defined on the basis of pulmonary function, emphysema has a patho-anatomic substrate. Chronic bronchitis on the other hand is defined clinically: productive cough of three months duration per year occurring in two successive years. Complete abstinence of smoking is a prerequisite for a meaningful anti-obstructive therapy. Beta-2-adrenergic stimulation and corticosteroids represent the treatment of choice. Beta-2-agonists are effectively complemented by anticholinergic drugs. Oral or parenteral corticosteroids should be used liberally for exacerbations. For prolonged treatment topical steroids are prescribed exclusively in order to prevent systemic side effects. The type of inhalation therapy (electric nebulizer, aerosol spray, insufflator) has to be adapted to the individual patient. Correct application of inhalation-technique is important. Topical steroids should be administered by means of a spacer chamber. Physical therapy is the most important adjuvant treatment. Selective respiration-training, a correction of breath-technique and autogenic bronchial drainage manoeuvres have to be learned in the setting of a rehabilitation program and are controlled frequently by the treating physician. The integration of all these measures into a treatment and rehabilitation plan is facilitated in a specialized clinic.
Role of the Alkyl Hydroperoxide Reductase ( <i>ahpCF</i> ) Gene in Oxidative Stress Defense of the Obligate Anaerobe <i>Bacteroides fragilis</i> (1999)

In this study we report the identification and role of the alkyl hydroperoxide reductase (ahp) gene in Bacteroides fragilis. The two components of ahp, ahpC, and ahpF, are organized in an operon, and the deduced amino acid sequences revealed that B. fragilis AhpCF shares approximately 60% identity to orthologues in other gram-positive and gram-negative bacteria. Northern blot hybridization analysis of total RNA showed that the ahpCF genes were transcribed as a polycistronic 2.4-kb mRNA and that ahpC also was present as a 0.6-kb monocistronic mRNA. ahpC and ahpCF mRNAs were induced approximately 60-fold following H(2)O(2) treatment or oxygen exposure of the parent strain but were constitutive in a peroxide-resistant strain. Further investigation using an ahpCF'::beta-xylosidase gene transcriptional fusion confirmed that ahpCF had lost normal regulation in the peroxide-resistant strain compared to the parent. The ahpCF mutant was more sensitive to growth inhibition and mutagenesis by organic peroxides than the parent strain, as determined by disk inhibition assays and the frequency of mutation to fusidic acid resistance. This finding suggests that the ahp genes play an important role in peroxide resistance in B. fragilis. Under anaerobic conditions, we observed increases in the number of spontaneous fusidic acid-resistant mutants of five- and sevenfold in ahpCF and ahpF strain backgrounds, respectively, and eightfold in the ahpCF katB double mutant strain compared to the parent and katB strains. In addition, ahpCF, ahpF, and ahpCF katB mutants were slightly more sensitive to oxygen exposure than the parent strain. Moreover, the isolation of a strain with enhanced aerotolerance and high-level resistance to alkyl hydroperoxides from an ahpCF katB parent suggests that the physiological responses to peroxide toxicity and to the toxic effects of molecular oxygen are overlapping and complex in this obligate anaerobe.
Digital planarity of rectangular surface segments (1994)

We generalize the concept of evenness which has been developed for digital straight lines. Evenness is a necessary and sufficient condition for a digital arc segment to be a digital straight line segment. We prove that evenness is also a necessary and sufficient condition for a rectangular surface segment to be a digital plane segment. This is not true for surface segments of arbitrary shape. To clarify the relation between shape and evenness we introduce the notion of a regular shape and of an arbitrarily extendable even set.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
Control of structures of deposited polymer films by ablation laser wavelength: Polyacrylonitrile at 308, 248, and 193 nm (1996)

Extensive control of structures of deposited polymer films has been realized when the films have been prepared on a quartz or KBr substrate by laser ablation of polyacrylonitrile (PAN) with 308 (XeCl), 248 (KrF), and 193 nm (ArF) excimer laser beams, as revealed by scanning electron microscopy, infrared spectroscopy, x-ray photoelectron spectroscopy, electron spin resonance, and x-ray diffraction measurements. The original structure of PAN is essentially retained for the films deposited by ablation at 308 nm. Deformation and elimination of nitrile groups occur for the films prepared by ablation at 248 and 193 nm, respectively. Furthermore, a remarkable power-dependent structural change has been observed at 248 nm; an increase in the laser power has led to ring closure of nitrile groups, resulting in the development of π-conjugated systems. In addition, a rather high electric conductivity on the order of 10−2S cm−1 has been given to the films deposited by ablation at 248 and 193 nm on reirradiation with lower-power excimer laser beams of 308 nm.
