Simple but effective techniques for NUMA memory management (1989)

Multiprocessors with non-uniform memory access times introduce the problem of placing data near the processes that use them, in order to improve performance. We have implemented an automatic page placement strategy in the Mach operating system on the IBM ACE multiprocessor workstation. Our experience indicates that even very simple automatic strategies can produce nearly optimal page placement. It also suggests that the greatest leverage for further performance improvement lies in reducing false sharing , which occurs when the same page contains objects that would best be placed in different memories.
Hybrid Intrusion Detection with Weighted Signature Generation over Anomalous Internet Episodes (2007)

This paper reports the design principles and evaluation results of a new experimental hybrid intrusion detection system (HIDS). This hybrid system combines the advantages of low false-positive rate of signature-based intrusion detection system (IDS) and the ability of anomaly detection system (ADS) to detect novel unknown attacks. By mining anomalous traffic episodes from Internet connections, we build an ADS that detects anomalies beyond the capabilities of signature-based SNORT or Bro systems. A weighted signature generation scheme is developed to integrate ADS with SNORT by extracting signatures from anomalies detected. HIDS extracts signatures from the output of ADS and adds them into the SNORT signature database for fast and accurate intrusion detection. By testing our HIDS scheme over real-life Internet trace data mixed with 10 days of Massachusetts Institute of Technology/Lincoln Laboratory (MIT/LL) attack data set, our experimental results show a 60 percent detection rate of the HIDS, compared with 30 percent and 22 percent in using the SNORT and Bro systems, respectively. This sharp increase in detection rate is obtained with less than 3 percent false alarms. The signatures generated by ADS upgrade the SNORT performance by 33 percent. The HIDS approach proves the vitality of detecting intrusions and anomalies, simultaneously, by automated data mining and signature generation over Internet connection episodes
Novel fire detection device for robotic fire fighting (2010)

This paper presents a novel fire detection device in the highly complicated urban environment, such as an office building, supermarket, school, etc. A robot for fire detecting and/or search and rescue needs to move fast while searching wide area. For this, we had developed an thermal image camera module which is capable of selectively acquiring very large field of view (FOV) - panoramic view - images or narrow field of view images from a single viewpoint, at video rates. An image processing and device controlling algorithm to detect a fire fastly and accurately was developed also. The developed device was tested in the indoor environments and the feasibility of the device was evaluated. We expect that the application of the proposed device is not limited to fire fighting. Its application will include a military, security and scientific field. For the further works, we will improve the performance of the detection algorithm in the proposed device and test it using a mobile platform in a realistic environment.
The developmental increase in ACh current densities on rat sympathetic neurons correlates with changes in nicotinic ACh receptor alpha-subunit gene expression and occurs independent of innervation (1994)

Determining factors that control the expression of neurotransmitter receptors and the mechanisms by which these factors operate is essential to understand how synapses form during development and how receptor numbers change in the adult. In this study, we have investigated one such factor, the influence of innervation, on the developmental expression of nicotinic ACh receptors (nAChRs) on neonatal rat sympathetic neurons, both in terms of ACh current densities, and in terms of mRNA levels for the transcripts that encode these receptors. To date, nine genes have been cloned that encode neuronal nAChRs subunits in mammals. We demonstrate that mRNA encoding five nAChR subunits, alpha 3, alpha 5, alpha 7, beta 2, and beta 4, are present in neonatal rat sympathetic neurons. We show that mRNA levels for alpha 3 and alpha 7 subunits increase by more than threefold over the first 2 postnatal weeks, a period when most synapses are forming on the neurons; however, we observed no significant change in mRNA levels for alpha 5, beta 2, or beta 4. Using whole-cell voltage-clamp techniques, we show that the increase in alpha-subunit mRNA correlates with increases in ACh current densities, which double over the same period. To investigate the role of innervation, we cut the preganglionic nerve at birth and measured subunit mRNA levels and ACh current densities in denervated neurons 1-2 weeks later. Our results indicate that the preganglionic nerve differentially affects the mRNA level for the five nAChR transcripts, yet it has little influence on the developmental increase in ACh current densities.

Gene Knockouts and Murine Development (1993)

A considerable quantity of data has been generated using the technique of in vivo gene knockout in mice, much of which is of relevance to the developmental biologist. Null mutations in Hox genes at the 3'-end of the clusters create complex irregularities at the rostral end of the embryo, including defects in the middle ear and the large blood vessels, suggesting that Hox genes may be involved in pattern specification of these structures in addition to the anteroposterior axis. Null mutations in oncogenes either cause wide pleiotropic effects, or act in a restricted manner on the haematopoietic system. Null mutations in growth factors and related molecules cause failure of proliferation in restricted areas of the embryo in some cases, but have little phenotype in others. There is as yet no null mutation which supports the idea that growth factors are involved in mesoderm induction in mammals. A surprising variety of genes have no null phenotype, or one less severe than might have been previously predicted on the basis of their known function in vitro and pattern of expression. This leads to the possibility that genetic redundancy exists in development.

Hybrid Swarm Algorithm for the Suppression of Incubator Interference in Premature Infants ECG (2013)

The premature infant Electrocardiography (ECG) is always contaminated by an electromagnetic interference caused by the incubator devices. This study describes the interference noise cancelling techniques for filtering of the corrupted infant ECG signal using the biological inspired Particle Swarm Optimization (PSO) algorithm. The active noise control system is designed using a adaptive learning ability of artificial neural network Back propagation algorithm. The neural weights are adapted based in PSO in an adaptive manner. In this study, the hybrid Particle Swarm Optimization-Back Propagation Neural Network (PSO-BPNN) feed forward algorithm is used for the Active Noise Control (ANC) of the fundamental electromagnetic interference in the incubators. The results showed the incubator noise can be significantly reduced using the developed hybrid PSO-BPNN algorithm. To implement this process of noise cancellation, the software used is MATLAB 7.10 with the help of neural network toolbox.

Bis-intercalative binding to DNA of novel bis(10-methyl)acridinium chlorides and its dependence on chain length of linker (1978)

The synthesis of a series of novel bis(10-methyl)acridinium compounds (both unsubstituted and the 6-chloro-2-methoxy substituted) linked by methylene bridges of lengths from (CH2)4 to (CH2)12 and in one case by spermine is described. Their ability to bind to duplex DNA was compared by their relative inhibition of E. coli DNA polymerase catalyzed DNA synthesis. It was determined that they function as DNA template inhibitors and do not affect the DNA polymerase directly. Their ability to function as bis-intercalators was assessed by a novel and convenient topoisomerase fluorescent assay. It was concluded that whereas the (CH2)4-linked compounds act only as monofunctional intercalators because of steric constraints the (CH2)6-, (CH2)8-, and (CH2)10-linked substituted bisacridinium compounds, as well as the (CH2)10- and (CH2)12- unsubstituted analogues, function as bis-intercalators with DNA.
Transform a NIAM conceptual schema into a EKNE relational database scheme (2002)

A system for enhancements of semantic methodologies for relational database design is described. In order to design a well-formed NIAM conceptual schema, dependency theory can be used as a heuristic tool to help the designer detect the derived fact types (FTs) in the NIAM conceptual schema. In order to design a minimal relational database schema, one can use dependency theory as a heuristic tool to find the candidate FTs for substitution, interact with the users to redesign the conceptual schema, and then transform it into an EKNF (elementary key normal form) relational database schema with the minimal number of relations. The proposed system is implemented using Turbo Pascal 5.5 on IBM PS2.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
The Inorganie Fluoride and Oxyfluoride Ferroelectrics (1997)

The ferroelectric fluorides belong to six families of type (NH4)2BeF4, BaMnF4, SrAlF5, Na2MgAlF7, K3Fe5F15 or Pb5Cr3F19. The oxyfluorides can be separated in two groups: i) the true oxyfluorides with a relatively high F/O value (K3MoO3F3, Na5W3O9F5, Pb5W3O9F10, Bi2TiO4F2, ...); ii) the compositions derived from ferroelectric oxides (perovskite, tetragonal tungsten bronze, pyrochlore, LiTaO3, ...) characterized by a continuous F-O substitution. The phase transitions and the physical properties are discussed. The origin of the spontaneous polarization is described structurally. The variations of the Curie temperature with the type of substitution are related to chemical bonding. The potential interest of these materials for applications is briefly given.
Improved coding techniques for preceded partial-response channels (1994)

A coset of a convolutional code may be used to generate a zero-run length limited trellis code for a 1-D partial-response channel. The free squared Euclidean distance, d/sub free//sup 2/, at the channel output is lower bounded by the free Hamming distance of the convolutional code. The lower bound suggests the use of a convolutional code with maximal free Hamming distance, d/sub max/(R,N), for given rate R and number of decoder states N. In this paper we present cosets of convolutional codes that generate trellis codes with d/sub free//sup 2/>d/sub max/(R,N) for rates 1/5/spl les/R/spl les/7/9 and (d/sub free//sup 2/=d/sub max/(R,N) for R=13/16,29/32,61/64, The tabulated convolutional codes with R/spl les/7/9 were not optimized for Hamming distance. Instead, a computer search was used to determine cosets of convolutional codes that exploit the memory of the 1-D channel to increase d/sub free//sup 2/ at the channel output. The search was limited by only considering cosets with certain structural properties. The R/spl ges/13/16 codes were obtained using a new construction technique for convolutional codes with free Hamming distance 4. Newly developed bounds on the maximum zero-run lengths of cosets were used to ensure a short maximum run length at the 1-D channel output.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
Seguimiento de embarazadas en alto riesgo de infección por virus del herpes simple (1994)

Follow-up of Pregnant Women at High Risk of Infection from Herpes Simplex virus The purpose of this study was to investigate the behavior of herpes simplex virus infection during the final weeks of pregnancy and at delivery in pregnant Chilean women at high risk for herpes infection. The study, carried out between 1988 and 1990, included 123 pregnant women seen at the Virology Clinic of the School of Medicine in Santiago, Chile, all of whom participated in an epidemiologic survey to identify seroconversion and diagnose primary herpetic infection. After the 34th week of pregnancy, or at delivery for those with primary herpetic infection, virus isolation was attempted. A total of 86 women completed the follow-up. In 59, the classification of “high-risk” was based on the existence of genital herpes; in 16, on prior herpes episodes; and in ll, on the development of the first episode of genital herpes during pregnancy. After week 34 of pregnancy, 21 of the women suffered some type of herpetic episode, while virus could not be isolated from 65. Vaginal delivery is recommended for asymptomatic women and cesarean delivery for those with symptoms or prodromal manifestations. The attempt should be made at the time of delivery to isolate the virus from asymptomatic women and those at high risk, in order to identify at-risk newborns and choose the most appropriate treatment in each case.

Modeling, scheduling, and prediction in wafer fabrication systems using queueing Petri net and genetic algorithm (2002)

Wafer fabrication is one of the most competitive manufacturing business in the world. In order to survive in such a strongly competitive environment, finding an effective schedule which can result in higher machine utilization and throughput rate, shorter cycle time, and lower WIP (work-in-process) inventory becomes a major task. Besides that, in order to help customers to make ordering decisions as well as to let the manager control the processing conditions of the fab, we need to predict some performance measures efficiently. We propose a modeling tool called queueing-Petri net (Q-PN) which combines the characteristics of queueing theory and Petri nets. It can be used to model various details of the manufacturing systems as well as to evaluate its performance very efficiently. Then, a general Q-PN model is presented to simulate the semiconductor manufacturing system. Based on this model, we propose a genetic algorithm (GA) based scheduler and an analysis-based predictor. In the GA scheduler, the chromosome represents a combination of scheduling policies, including lot release policies, machine selection rules, dispatch rules and batch rules. So, when the GA finishes its optimization process, an optimal scheduling policy is produced. As for the predictor, because it inherits the analytical property of queueing theory from the Q-PN model, we can use it to predict those performance measures efficiently such as the exact due date of some particular lot.
Effort Estimation in Global Software Development Projects: Preliminary Results from a Survey (2010)

Global Software Development (GSD) has intensified over the past years. Many reasons drove this development practice rise, where reducing development costs can be highlighted. In this context, software development effort estimation plays a very important role to achieve this goal of reducing costs. Once the effort required to develop software is a key component of the cost of development, the correct application of effort estimation techniques is crucial for the success of these projects. However, the current set of effort estimation techniques and models have been used without a clear definition of what has to be different when such techniques or models are used in the context of GSD projects. This paper presents preliminary results towards the understanding of effort estimation in GSD projects. The results found indicate that the teams don't have clear criteria to guide the selection of an effort estimation technique for a certain project. In addition, we can not correlate the effort estimation technique being used and the number of locations involved in a distributed project.

Comparison between Bubble CPAP and Ventilator-derived CPAP in Rabbits (2008)

Our results suggest that B-CPAP seems to be superior to V-CPAP in terms of its effect on arterial blood gases and vital signs. We speculate that B-CPAP could have certain protective effects that better preserve both arterial blood gases and vital signs when compared to V-CPAP. However, the results of this study still need to be tested by clinical study.

DNA-Assisted β-phase Nucleation and Alignment of Molecular Dipoles in PVDF Film: A Realization of Self-Poled Bioinspired Flexible Polymer Nanogenerator for Portable Electronic Devices (2015)

A flexible nanogenerator (NG) is fabricated with a poly(vinylidene fluoride) (PVDF) film, where deoxyribonucleic acid (DNA) is the agent for the electroactive β-phase nucleation. Denatured DNA is co-operating to align the molecular -CH2/-CF2 dipoles of PVDF causing piezoelectricity without electrical poling. The NG is capable of harvesting energy from a variety of easily accessible mechanical stress such as human touch, machine vibration, football juggling, and walking. The NG exhibits high piezoelectric energy conversion efficiency facilitating the instant turn-on of several green or blue light-emitting diodes. The generated energy can be used to charge capacitors providing a wide scope for the design of self-powered portable devices.
