Effective and Efficient Data Aggregation Technique for Common Web Log XML Format for Digital Forensics Investigation (DFI)

---In this paper talks about the process of data aggregation. Data aggregation is one of the method which is mostly used in reducing the size of the records set. Reduced data set could be helpful at many places. This reduction of record set can be done through data aggregation method. This data aggregation ca n be of two types as lossy and lossless. Here the proposed work is best on lossy technique. This lossy technique reduces the data for very large extends but it is useful only when original data regeneration is not required. The proposed work would not require any regeneration of original record set. This feature allows to use lossy aggregation technique. The proposed work is implemented in MATLAB.
An adaptive scheme for compensation of loss of effectiveness of flight control effectors

In this paper we present two stable adaptive tracking control algorithms for compensation of loss of effectiveness of control effectors in flight control applications. The overall approach is based on suitable failure parameterization, control law and adaptive algorithm design, and Lyapunov analysis of the properties of the overall system. The proposed adaptive algorithms are based on parameter-adaptive and variable-structure control approaches. It is shown that, in both cases, the overall system is stable and the tracking error converges to zero asymptotically. The properties of the proposed algorithms are illustrated through simulations of the F/A-18C/D aircraft in the presence of multiple control effector failures. The proposed algorithms appear to be promising tools for effective on-line compensation of multiple flight critical failures.
Cognitive engineering, cognitive augmentation, and information display

Abstract— From a perspective of cognitive engineering, this paper presents eight principles of good display design based on human cognition: (1) displays that divide attention will increase the cognitive load on working memory; (2) displays that continuously present the same information may compensate for the decay of short‐term memory; (3) displays that assist the viewer in mentally chunking information will decrease the cognitive load on working memory; (4) displays that present icons or images to direct attention to important visual stimuli will likely minimize inattentional blindness; (5) displays that help minimize attentional distractions and help focus attention on a given task will minimize the burden on working memory; (6) displays that present cues composed of strong singletons will capture and engage exogenous attention; (7) displays that help the viewer make a mental connection between an analogue and a target will assist in the induction of analogical reasoning; (8) displays that present over time multiple exposures consisting of statistical regularities may promote implicit learning and expertise development. Thus, information displays of the future can systematically engage high‐level human cognitive processes for purposes of improving human performance on a variety of tasks found in education, the military, and many other applications.
Development of an algorithm for heartbeats detection and classification in Holter records based on temporal and morphological features

In this work a detection and classification algorithm for heartbeats analysis in Holter records was developed. First, a QRS complexes detector was implemented and their temporal and morphological characteristics were extracted. A vector was built with these features; this vector is the input of the classification module, based on discriminant analysis. The beats were classified in three groups: Premature Ventricular Contraction beat (PVC), Atrial Premature Contraction beat (APC) and Normal Beat (NB). These beat categories represent the most important groups of commercial Holter systems. The developed algorithms were evaluated in 76 ECG records of two validated open-access databases "arrhythmias MIT BIH database" and "MIT BIH supraventricular arrhythmias database". A total of 166343 beats were detected and analyzed, where the QRS detection algorithm provides a sensitivity of 99.69 % and a positive predictive value of 99.84 %. The classification stage gives sensitivities of 97.17% for NB, 97.67% for PCV and 92.78% for APC.
Computer-Assisted and Peer Assessment: A Combined Approach to Assessing First Year Laboratory Practical Classes for Large Numbers of Students

Abstract Providing fair assessment with timely feedback for students is a difficult task with science laboratory classes containing large numbers of students. Throughout our Faculty, such classes are assessed by short-answer questions (SAQs) centred on principles encountered in the laboratory. We have shown recently that computer-assisted assessment (CAA) has several advantages and is well received by students. However, student evaluation has shown that this system does not provide suitable feedback. We thus introduced peer assessment (PA) as a complementary procedure. In October 2006, 457 students registered for a first-year practical unit in the Faculty of Life Sciences, University of Manchester. This unit consists of ten compulsory biology practical classes. The first four practicals were assessed using PA; the remaining six practicals were assessed by CAA and marked by staff or postgraduate student demonstrators. The reliability and validity of PA were determined by comparing duplicate scripts and by staff moderation of selected scripts. Student opinions were sought via questionnaires. We show that both assessments are valid, reliable, easy to administer and are accepted by students. PA increases direct feedback to students, although the initial concerns of student groups such as mature and EU/International students need to be addressed using pre-PA training.
A 1 Gb DRAM for file applications

A number of large capacity DRAMs have been developed recently for file applications because data storage devices play an important role in high-speed communication and graphic systems. Such file memories must have low power dissipation, high data transfer rate and low cost. A low chip-yield problem is reported to occur in the manufacture of large capacity DRAMs. To address both device requirements and yield limitations, new circuit technologies have been developed for 1 Gb DRAMs. By implementing a time-shared offset cancel sensing scheme and adopting a diagonal bit-line (DBL) cell, the chip size is reduced to 70% of that of a conventional DRAM. A defective word-line Hi-Z standby scheme and a flexible multi-macro architecture produces about twice the yield as that resulting from conventional architecture. 32 b I/Os with a pipeline circuit technique realizes a 400 MB/s data transfer rate. A 1 Gb DRAM with these features uses 0.25 /spl mu/m CMOS.

Traditional Usages and Phytochemical Screenings of Selected Zingiberaceae from Central Sulawesi, Indonesia

Background: Zingiberaceae is one of the significant components of the herbaceous ground flora of Southeast Asia tropical forests. This family includes some medicinally important species, in particular the members of genera of Alpinia, Curcuma, Etlingera and Zingiber (Van Balgooy, 2001). Objective: to identify the traditional usages and evaluate for phytochemical screening of selected Zingiberaceae from Central Sulawesi, Indonesia. Material and Methods: Zingiberaceae samples were collected from the Lore Lindu National Park (LLNP), Central Sulawesi Indonesia and its surroundings and evaluated for their phytochemical contents by using TLC method with particular spraying reagents. Results: the plants were used by the local ethnics for different daily and medicinal purposes. All part of each selected species of Zingiberaceae contain flavonoid, tannins, saponins, triterpenoid and alkaloid although steroids were only found in the leaves of Etlingera flexuosa, Curcuma mangga and Alpinia galanga. Alkaloids were only found in the rhyzome of Etlingera flexuosa, Curcuma aerugynosa, Zingiber montanum. Besides it was also detected in leaves of both Alpinia rubricaulis and Etlingera acanthoides. Additionally, Alkaloids were also discovered in the stem of Ammomum aculeata, Alpinia galanga and Curcuma mangga.
Applying MLP and RBF classifiers in embedded condition monitoring and fault diagnosis systems

In this paper, results are presented from a comprehensive series of studies aimed at assessing the suitability of multilayered perceptron (MLP) and radial basis function (RBF) networks for use in embedded, microcontroller-based, condition monitoring and fault diagnosis (CMFD) applications. Our assessment criteria include the performance of each classifier on a range of CMFD-related problems, such as situations where there may be multiple faults present simultaneously, or where ‘unknown’ faults may occur. In addition, the processor and memory requirements of each classifier are compared and discussed. On the basis of the results obtained in these studies, it is argued that each form of classifier has both strengths and weaknesses, and that neither is suitable for use in all CMFD applications. The paper concludes by demonstrating that, where memory and processor limits allow, the best performance may be obtained through use of a fusion classifier containing both MLP and RBF components.
Effectiveness of computer-aided learning as a direct replacement for lecturing in degree-level electronics

The application of computer-aided learning as a direct replacement for, as opposed to an adjunct to, lecturing is still in its infancy in higher education. This paper examines some of the reasons for its slow uptake and then describes a project to develop courseware for a large proportion of the electronic engineering syllabus within several UK higher education institutions. The first modules to be completed cover the area of computer engineering. The authors describe the philosophy and design of this courseware, and then report a series of tests in which the examination performance of students using it was compared with that of control groups taught in traditional lectures. The results clearly suggest that carefully designed courseware can lead to a large reduction in teaching time, with no significant difference in learning. They then describe the development of this courseware into what is believed to be the first degree-level electrical engineering course module to be replaced in its entirety by computer-based self-teaching. They discuss the impact of this development on the course structure, and show how the time gained has been used for additional practical work and tutorial support.

Changes in the Levels of Some Biochemical Parameters in the Serum of Children in Response to the Giardiasis Infection

Giardiasis is one of the most common intestinal protozoan infections worldwide. The study aimed to determine the levels of a number of biochemical parameters in the sera of children with giardiasis without receiving any medication for the treatment of giardiasis or intestinal helminthic infections in the previous 7 days. The study conducted 34 (19 females and 15 males) children and 34 (18 females and 16 males) healthy children as a control group. The mean ages of infected children and control groups were 8 ± 2 and 7 ± 2 years, respectively. Serum levels of aspartate aminotransferase (AST), alanine aminotransferase (ALT), creatinine, urea, sodium, potassium, uric acid, and albumin were determined. AST level in males was significantly higher than healthy children control (14.20 ± 1.896 and 10.06 ± 0.699), respectively (P < 0.05), and no significant difference in females was noticed whereas the significant increases in ALT level were found when compared to control (12.43 ± 0.806 and 8.666 ± 0.449), for female, respectively, whereas no significant change in males was observed. Creatinine levels showed significant decrease in females when compared to control (57.72 ± 1.170 and 73.37 ± 1.635) (P ≤ 0.001), respectively.
Machine perception and learning of complex social systems

The study of complex social systems has traditionally been an arduous process, involving extensive surveys, interviews, ethnographic studies, or analysis of online behavior. Today, however, it is possible to use the unprecedented amount of information generated by pervasive mobile phones to provide insights into the dynamics of both individual and group behavior. Information such as continuous proximity, location, communication and activity data, has been gathered from the phones of 100 human subjects at MIT. Systematic measurements from these 100 people over the course of eight months have generated one of the largest datasets of continuous human behavior ever collected, representing over 300,000 hours of daily activity. In this thesis we describe how this data can be used to uncover regular rules and structure in behavior of both individuals and organizations, infer relationships between subjects, verify selfreport survey data, and study social network dynamics. By combining theoretical models with rich and systematic measurements, we show it is possible to gain insight into the underlying behavior of complex social systems. Thesis Supervisor: Alex P.

Simulation of a phosphene field based visual prosthesis

A visual prosthesis for the blind that is based on electrical stimulation of the visual cortex requires the development of an array of electrodes. To establish design specifications for such an electrode array, psychophysical experiments were concluded with normally sighted subject wearing a portable phosphene simulator. The simulator consists of a small video camera, a monitor masked by an opaque perforated film, and optical lenses. The visual angle subtended by the masked monitor is 1.7 degrees or less. Visual acuity and reading rate were measured as function of the number of pixels and their spacing. The results indicate that a phosphene image produced by 600 electrodes implanted in a 1-cm/sup 2/ area near the foveal projection on the visual cortex should provide a limited but useful visual sense for the profoundly blind. <<ETX>>
Thermal-aware test scheduling using network-on-chip under multiple clock rates

The increasing trend in the number of cores on a single chip has led to scalability and bandwidth issues in bus-based communication. Network-on-chip (NoC) techniques have emerged as a solution that provides a much needed flexibility and scalability in the era of multi-cores. This article presents an optimal integer linear programming (ILP) formulation and a simulated annealing (SA) solution to thermal and power-aware test scheduling of cores in an NoC-based SoC using multiple clock rates. The methods have been implemented and results on various benchmarks are presented.

Sustaining online teacher professional development through community design

Purpose – The purpose of this paper is to explore the role of community of practice in sustaining teachers' participation in a blended (face‐to‐face and online) professional development course.Design/methodology/approach – A longitudinal multiple‐case study methodology was used in researching groups of five teachers in Australia and four teachers in the UK. The two groups independently participated in an initial face‐to‐face training day and then completed the professional development course via an online learning environment (Blackboard). The course was designed to facilitate community of practice cohesion. Data collection included surveys, data mining of online activity, discussion forums and e‐mails, and semi‐structured interviews.Findings – The paper finds that the participants of both case studies demonstrated sustained engagement for more than twice the minimum requirement. While the Australian case study was sustained through a community‐defined regime of participation, the UK case study increasing.
The Skills That Technical Communicators Need: An Investigation of Technical Communication Graduates, Managers, and Curricula

This study examines the skills that recent technical communication graduates and managers believe technical communication students need before entering business and industry as new technical communicators. Through questionnaires and interviews with recent graduates and managers of technical communication departments as well as an analysis of the participating schools' curricula, this study suggests areas where technical communication may need more preparation, including business operations, project management, problem-solving skills, and scientific and technical knowledge. Further research is needed at local, state, and national levels to analyze technical communication undergraduate curricula along with responses from recent graduates of technical communication programs and managers of technical communication programs. Only through continued research can we ensure that future technical communicators receive an education that eases their transition into the world of business and industry.
Effect of Adding Dexmedetomidine versus Fentanyl to Intrathecal Bupivacaine on Spinal Block Characteristics in Gynecological Procedures: A Double Blind Controlled Study

Problem statement: The purpose of this study was to evaluate the onset and duration of sensory and motor block as well as operative analgesia and adverse effects of Dex Metedo Midine (DXM) or fentanyl given intrathecally with plain 0.5% bupivacaine for spinal anesthesia. Approach: seventy six patients classified as American Society of Anesthesiologists (ASA) status I, II and III scheduled for vaginal hysterectomy, vaginal wall repair and tension free vaginal tape were prospectively studied. Patients were randomly allocated to receive intrathecally either 10 mg isobaric bupivacaine plus 5 µg dexmetedomidine (group D n = 38) or 10 mg isobaric bupivacaine plus 25 mg fentanyl (group F n = 38), the onset time to reach peak sensory and motor level, the regression time for sensory and motor block, hemodynamic changes, and side effects were recorded. Results: Patients in group D had significant longer sensory and motor block times than patients in group F. the mean time of sensory regression to S1 was 274±73 min in group D and 179±47 min in group F (P < 0.001). The regression time of motor block to reach modified Bromage 0 was 240±60 min in group D and 155±46 min in group F (P< 0.001). The onset times to reach T10 dermatome and to reach peak sensory level as well as onset time to reach modified Bromage 3 motor block were not significantly different between the two groups. Conclusion: In women undergoing vaginal reconstructive surgery under spinal analgesia, 10 mg plain bupivacaine supplemented with 5 µg dexmetedomidine produces prolonged motor and sensory block compared with 25 µg fentanyl.
Study on modeling of spray cooling for spent fuel pool accidents

ABSTRACT In Japan, spray equipment is prepared in spent fuel pools (SFP) in accordance with the regulatory requirements to mitigate fuel damage in the event that the water level of SFP cannot be maintained. In order to evaluate the spray coolability of fuel assemblies in SFP accidents, the spray cooling experiments were conducted under the SFP conditions. The experimental facility contains one mock-up BWR fuel assembly with full-length 7 × 7 heater rods in a mock-up SFP rack. The measured surface temperatures indicate that the spray injection results in the top-down quench and the precursory cooling, which are consistent with the spray-cooling mechanism that has been revealed by previous studies investigating reactor core spray. Further, the numerical simulations of the experiments were conducted using the TRACE code to examine the applicability of system codes for evaluating the spray coolability of SFPs. Although the TRACE calculation with a simple analytical model reproduced the top-down quench by spray injection as observed in the experiments, some qualitative differences were found between the experiments and calculations. The causes of these differences were revealed and the applicability of system codes were discussed.
A fuzzy logic controlled genetic algorithm for optimal electrical distribution network reconfiguration

Electrical distribution network reconfiguration is a complex optimization process aimed at finding a radial operating structure that minimizes the system power loss while satisfying operating constraints. This paper presents the application of a fuzzy controlled real coded genetic algorithm to solve the reconfiguration problem. Two controllers are used to adaptively adjust the crossover and mutation probabilities based on the fitness function. Simulation results are presented for the proposed method which is compared to a genetic algorithm with fixed crossover and mutation probabilities.
On the fine vertical structure of the low troposphere over the coastal margins of East Antarctica

Abstract. In this study, 8 years of high-resolution radiosonde data at nine Antarctic stations are analysed to provide the first large-scale characterization of the fine vertical structure of the low troposphere up to 3 km altitude over the coastal margins of East Antarctica. Radiosonde data show a large spatial variability of wind, temperature and humidity profiles, with different features between stations in katabatic regions (e.g., Dumont d'Urville and Mawson stations), stations over two ice shelves (Neumayer and Halley stations) and regions with complex orography (e.g., McMurdo). At the Dumont d'Urville, Mawson and Davis stations, the yearly median wind speed profiles exhibit a clear low-level katabatic jet. During precipitation events, the low-level flow generally remains of continental origin and its speed is even reinforced due to the increase in the continent–ocean pressure gradient. Meanwhile, the relative humidity profiles show a dry low troposphere, suggesting the occurrence of low-level sublimation of precipitation in katabatic regions but such a phenomenon does not appreciably occur over the ice shelves near Halley and Neumayer. Although ERA-Interim and ERA5 reanalyses assimilate radiosoundings at most stations considered here, substantial – and sometimes large – low-level wind and humidity biases are revealed but ERA5 shows overall better performance. A free simulation with the regional polar version of the Weather Research and Forecasting model (Polar WRF) (at a 35 km resolution) over the entire continent shows too-strong and too-shallow near-surface jets in katabatic regions especially in winter. This may be a consequence of an underestimated coastal cold air bump and associated sea–continent pressure gradient force due to the coarse 35 km resolution of the Polar WRF simulation. Beyond documenting the vertical structure of the low troposphere over coastal East Antarctica, this study gives insights into the reliability and accuracy of two major reanalysis products in this region on the Earth. The paper further underlines the difficulty of modeling the low-level flow over the margins of the ice sheet with a state-of-the-art atmospheric model.
