STRATEGIC MANAGEMENT TO IMPROVE GRADUATED GRADUATION TO ENCOURAGE EMPLOYMENT RESERVES IN VOCATIONAL SCHOOLS IN BANDUNG DISTRICT (2019)

Research problems faced by Vocational High Schools (VHS) in Bandung Regency include the incompatibility of the expertise competencies learned at the School with the competencies needed by the business and industrial world (BIS). One indicator of this gap is the low absorptive capacity of School graduates by the business world and the industrial world (BIS). The low absorptive capacity of labor graduates from Vocational High Schools (VHS) by the business and industrial world causes limited employment. This condition tends to result in open unemployment. The purpose of this study is to obtain an empirical picture of the implementation of strategic management to improve the quality of graduates to encourage the absorption of work. The results of this study are that the general description of strategic management that has been carried out at the Vocational High School (VHS) to improve the quality of graduates encourage absorption of work done in stages, namely 1) SWOT Analysis, 2) Formulation Phase which includes vision, mission, 3) Implementation Phase which includes setting annual targets, managing policies 4) Evaluation Phase which includes strategic activities in the external and internal environment. 5) Factors supporting the strategy in improving the quality of graduates to encourage the absorption of graduates in the business world and industry.
Improved PCA methods for process disturbance and failure identification (1999)

Abstract Principal component analysis (PCA) is a powerful technique for constructing reduced‐order models based on process measurements, obtained by the rotation of the measurement space. These models can be subsequently utilized for chemical‐process monitoring, particularly for disturbance and failure diagnosis. Since the standard PCA procedure does not account for the time‐dependent relationships among the process variables, this leads to poorer disturbance isolation capability in dynamic applications. A simple idea, in which the last s PCA scores are recursively summed and used to construct descriptive statistics for process monitoring, is presented. Analytically, it is shown that the disturbance resolution afforded is enhanced as a result. Resolution is improved further through the use of an algorithm that enhances the correlations between the input and output variables through optimal time shifting. An overall strategy for on‐line monitoring developed includes disturbance identification through mapping. The approach is demonstrated by two industrially relevant case studies.
Antibody Responses to La Sota Strain Vaccines of Newcastle Disease Virus in Ostriches (Struthio camelus) as Detected by Enzyme-Linked Immunosorbent Assay (2000)

Because of the fact that South Africa is a Newcastle disease virus (NDV)-endemic country, major concerns exist that the export of ostrich meat could transmit velogenic strains of this disease. The ability to transmit the virus could be reduced by effective vaccination of South African ostriches. In this study, two vaccination trials were conducted to assess serum antibody production in response to vaccination with La Sota strain NDV vaccines. To this end, a commercially available chicken anti-NDV enzyme-linked immunosorbent assay (ELISA) was modified for the detection of anti-NDV antibodies in ostrich serum. The results obtained with this ELISA were verified by comparison with an indirect ELISA. In the first trial, ostriches were immunized subcutaneously four times with different volumes of an inactivated vaccine and their immune response was determined from 2.5 mo up to the ideal slaughter age of 14 mo. Results indicated that ostriches responded in a dose-dependent manner and gave support for the vaccination schedule currently recommended to South African farmers. In a second trial, immunization by eyedrop with a live La Sota vaccine of 5-wk-old ostriches did not elicit a humoral immune response. The results indicate that it is highly unlikely that ostriches that have been vaccinated according to the recommended vaccination schedule can transmit the virus.
Hydroboration (2000)

Abstract The hydroboration reaction and transformations of its organoborane products are described. The mechanism and the chemo‐, regio‐, and stereoselectivity of the hydroboration reaction are presented, as well as the synthesis and characteristics of the most common hydroborating agents. Transformations of organoboranes may involve carbon‐hetero atom bond formation and lead to stereoselective synthesis of organic halides, amines, aziridines, sulfur, selenium, and mercury compounds. Hydroboration‐protonolysis is a nonocatalytic method of cis‐hydrogenation of multiple bonds. Hydroboration‐oxidation is a standard method for cis‐anti‐Markovnikov hydroxylation of multiple bonds. Carbon‐carbon bond formation can be accomplished by transformation of organoboranes through coupling of groups attached to boron, cross‐coupling of organoboranes with organic halides, organoborate rearrangements providing access to alkynes, ( E )‐ and ( Z )‐alkenes, ( E,E )‐, ( E,Z )‐, ( Z,Z )‐dienes, and enynes. Single‐carbon insertion reactions include carbonylation, cyanidation, and the DCME and related reactions. Other reactions include α‐ and β‐alkylation of carbonyl compounds, the addition of alkynyl, alkenyl, and allylic boranes to aldehydes, leading to proparylic alcohols and stereodefined allylic and homoallylic alcohols, boron‐stabilized carbanions, the boron Wittig reaction, and concerted reactions of allylic and vinylic boranes. Contrathermodynamic isomerization of olefins is discussed. The synthesis of boron‐containing polymers and of isotopically labeled compounds is covered. Asymmetric synthesis via chiral organoboranes is covered in detail.
Elevated NMDA receptors in Parkinsonian striatum (1992)

Dopamine-glutamate interactions contribute to normal striatal function and have been implicated in neurotoxicity at nigrostriatal dopamine (DA) terminals. The present study examined the striata of idiopathic Parkinson's disease (PD) patients and age-matched controls for regional differences in the DA transporter and binding to N-methyl-D-aspartate (NMDA) receptors. [3H]Mazindol labeling of the DA transporter was reduced by 70-80% in the caudate and putamen of PD patients, with reductions being more extensive dorsally than ventrally. In contrast, L-[3H]glutamate binding to NDMA-sensitive receptors was 20-40% higher in PD cases than in controls. These findings raise the possibility that modifications occur within corticostriatal glutamate synapses of PD patients, possibly as a consequence of reduced nigrostriatal DA activity.
Identification Method of Sports Throwing Force Based on Fuzzy Neural Network (2013)

In order to speed up the defects of the neural network computing and recognition, the essay proposes the information identification method research of sports throwing force based on the fuzzy neural network model. Firstly, I use the information, which is the combination of the wavelet transformation and the fuzzy neural network, to identify the new method combining and make the noise-suppressed processing of information. Then, according to the athlete’s throwing action and the extraction of signal processing characteristics, as well as the analysis of the fuzzy neural network algorithm. Finally, in order to verify the effectiveness of the proposed algorithm, I make analysis for the experimental results, which indicates that using this algorithm can not only have less noise than the traditional algorithm, but also have less number of the neural network computation. Besides, its recognition speed and accuracy is also higher.
Quasi-succinct indices (2013)

Compressed inverted indices in use today are based on the idea of gap compression: documents pointers are stored in increasing order, and the gaps between successive document pointers are stored using suitable codes which represent smaller gaps using less bits. Additional data such as counts and positions is stored using similar techniques. A large body of research has been built in the last 30 years around gap compression, including theoretical modeling of the gap distribution, specialized instantaneous codes suitable for gap encoding, and ad hoc document reorderings which increase the efficiency of instantaneous codes. This paper proposes to represent an index using a different architecture based on quasi-succinct representation of monotone sequences. We show that, besides being theoretically elegant and simple, the new index provides expected constant-time operations, space savings, and, in practice, significant performance improvements on conjunctive, phrasal and proximity queries.
Aspect-Oriented Sentiment Analysis of Customer Reviews Using Distant Supervision Techniques (2013)

The opinions and experiences of other people constitute an important source of information in our everyday life. For example, we ask our friends which dentist, restaurant, or smartphone they would recommend to us. Nowadays, online customer reviews have become an invaluable resource to answer such questions. Besides helping consumers to make more informed purchase decisions, online reviews are also of great value to vendors, as they represent unsolicited and genuine customer feedback that is conveniently available at virtually no costs. However, for popular products there often exist several thousands of reviews so that manual analysis is not an option. In this thesis, we provide a comprehensive study of how to model and automatically analyze the opinion-rich information contained in customer reviews. In particular, we consider the task of aspect-oriented sentiment analysis. Given a collection of review texts, the task’s goal is to detect the individual product aspects reviewers have commented on and to decide whether the comments are rather positive or negative. Developing text analysis systems often involves the tedious and costly work of creating appropriate resources --- for instance, labeling training corpora for machine learning methods or constructing special-purpose knowledge bases. As an overarching topic of the thesis, we examine the utility of distant supervision techniques to reduce the amount of required human supervision. We focus on the two main subtasks of aspect- oriented review mining: (i) identifying relevant product aspects and (ii) determining and classifying expressions of sentiment. We consider both subtasks at two different levels of granularity, namely expression vs. sentence level. For these different levels of analysis, we experiment with dictionary-based and supervised approaches and examine several distant supervision techniques. For aspect detection at the expression level, we cast the task as a terminology extraction problem. At the sentence level, we cast the task as a multi-label text categorization problem and exploit section headings in review texts for a distant supervision approach. With regard to sentiment analysis, we present detailed studies of sentiment lexicon acquisition and sentiment polarity classification and show how pros and cons summaries of reviews can be exploited to reduce the manual effort in this context. We evaluate our approaches in detail, including insightful mistake analyses. For each of the tasks, we find significant improvements in comparison to relevant state-of-the-art methods. In general, we can show that the presented distant supervision methods successfully reduce the required amount of human supervision. Our approaches allow to gather very large amounts of labeled data --- typically some orders of magnitude more data than possible with traditional annotation. We conclude that customer review mining systems can benefit from the proposed methods.
Lyapunov Stability of Linear Predictor Feedback for Time-Varying Input Delay (2010)

For linear time-invariant systems with a time-varying input delay, an explicit formula for predictor feedback was presented by Nihtila in 1991. In this note we construct a time-varying Lyapunov functional for the closed-loop system and establish exponential stability. The key challenge is the selection of a state for a transport partial differential equation, which has a non-constant propagation speed, and which is the basis of the stability analysis. We illustrate the design and its conditions with several examples. We also develop an observer equivalent of the predictor feedback design, for the case of time-varying sensor delay.
Phased arrays composed of antennas with steerable patterns (2002)

Traditional narrowband phased arrays consist of fixed antenna elements with adjustable complex weights for scanning the beam and controlling the beam shape. This paper investigates the improvements that can be obtained by steering the individual antenna patterns in addition to adjusting the array weights. Such steering of the antenna element patterns can be achieved by mechanical rotation or by an electronic mechanism. The fundamental issues in the design of this novel phased array are identified, and numerical simulations of beampatterns are included to illustrate the results.
An Innovative New Approach to Animal Care (2018)

Agricultural communities in rural areas often difficulty to attain expedient information and resources for their animal health issues. Most veterinarians are usually more than an hour away from the farmers, and in most cases animal health issues are only addressable through phone conversation. Advances in technology have enabled many human health problems to be investigated through telemedicine approaches, and it is believed that a similar approach could improve access and quality of veterinary care, especially in remote locations. The appropriate application of telemedicine can enhance animal care in rural communities by facilitating expedient communication, diagnostics, and possible treatment recommendations, client education improvement, vet visit scheduling, and other tasks. In addition, a telemedicine system could be linked to a strong distance education program that could provide multi-media resources for consumers so that they cannot just solve a crisis, but they can be better informed and thereby prevent medical crises. This project seeks to expand a web-based system and smart device app that will serve as a distance learning and a telemedicine tool to assist farmers in getting immediate support and reaching veterinary care professionals and extension agents. We believe that this service will be a powerful tool to assist animal producers in managing their animals, and to provide them the ability to obtain possible solution for problem they may encounter. We accomplish this by providing access to a database with any smart media device. This database contains simple to understand information with accompanying videos and pictures.
Deconstructing the Framers' Right to Property: Liberty's Daughters and Economic Rights (2000)

Deconstruction is a method for exposing hidden assumptions, that which is taken for granted, unquestioned. This Article draws on this method first to explain how the right to property, as understood by the Framers, became the hidden, unquestioned assumption of the Bill of Rights. Second, this Article draws on deconstruction to "unpack" the right to property to reveal the lesser-subsumed economic rights it takes for granted. It argues that the right to property and economic rights are iterations of the same rights, from the perspectives of the "haves" and the "have-nots," respectively. Recent work by women's historians makes it possible to use late eighteenth century women, one of the most conspicuously neglected groups of have-nots at the time, as a case study. This analysis shows how the denial of economic rights by culture and social custom, as well as by law, progressively distances civil and political rights. Ultimately, the denial of economic rights makes the legal proscription of civil and political rights unnecessary because, as a practical matter, these rights become unimaginable.

Association of HLA antigens with alcoholic disease. (1988)

A sample of 30 alcoholic patients, selected according to a rigorous criterion, was compared with two samples of the general population with respect to the distribution of HLA antigens. The sole inclusion criterion was the presence of signs and symptoms of an alcohol withdrawal syndrome. The alcoholic sample did not differ from the general population sample with respect to ABO blood group distribution, and had minimal evidence of alcoholic liver disease. The alcoholic group showed highly significant differences from the two general population samples with respect to the HLA system, consisting of a much higher frequency of HLA B40 and DR4 antigens and a much lower frequency of DR3. The results are consistent with the view that alcoholism may have a precise genetic determination.
Strong Tracking of a H-Infinity Filter in Lithium-Ion Battery State of Charge Estimation (2018)

The accuracy of state-of-charge (SOC) estimation, one of the most important functions of a battery management system (BMS), is the basis for the proper operation of an electric vehicle. This study proposes a method for accurate SOC estimation. To achieve a balance between accuracy and simplicity, a second-order resistor–capacitor equivalent circuit model is applied before the algorithm is deduced, and the parameters of the established model are determined using a fitting technique. Battery state space equations are then described. A strong tracking H-infinity filter (STHF) is proposed based on an H-infinity filter (HF) and a strong tracking filter. By introducing a suboptimal fading factor, the STHF approach can use the relevant information in the estimation residual sequence to update the estimation results. To verify the robustness of this approach, battery test experiments are performed at different temperatures on lithium-ion batteries. Finally, the SOC estimation results obtained using the STHF suggest that the STHF method exhibits high robustness against the measured noises and initial error. For comparison, the estimation results of the commonly used extended Kalman filter (EKF) and HF methods are also displayed. It is suggested that the proposed STHF approach obtains a more accurate SOC estimation.

These results suggest that the cinnamon extracts can be used as food antioxidant together with the improvement of food palatability. Further studies are in processing of analysing the sinergic association of extracts with synthetic antioxidant and to identify compounds with antioxidant activity in cinnamon extracts.
Synthesis and Kinetics of Highly Energetic Intermediates by Micromixers: Direct Multistep Synthesis of Sodium Nitrotetrazolate (2010)

A modular silicon micromixer is designed and fabricated for high-flow rapid mixing at a wide range of reaction conditions. The mixer operates by splitting two inlet flows into a large number of channels, interdigitating them, and constricting the laminated flow to create submicrometer diffusion lengths. Mixing is quantified using the Villermaux−Dushman method, with UV−vis detection of the photoactive species, and compared against a commercial micromixer. Micromixers and tubing are then used to perform a quantitative kinetic study of the direct two-step synthesis of sodium nitrotetrazolate (NaNT) by a Sandmeyer type reaction via a reactive diazonium intermediate. Orders of reactions and temperature dependence of both steps, as well as pH and ionic strength dependence of the second step, are evaluated. Successful production of 4.4 g/h of NaNT in solution is ultimately achieved in a compact footprint using the kinetic data, verifying the potential for scaling to typical production amounts.
Chopper controlled resistors in VSC-HVDC transmission for WPP with full-scale converters (2009)

Large and distant offshore wind power plants can be efficiently connected to the onshore power grid network using VSC-HVDC (Voltage Source Converter based HVDC) transmission. Chopper controlled resistors can be used to limit the DC line over-voltage when there is a fault on the onshore AC grid and power transfer to the grid is obstructed. Considering the development of full scale converter based wind turbine generators (WTG), use of unit rated chopper controlled resistors for each of the full scale AC-DC-AC converter system of the individual turbines has been proposed in place of the one on the HVDC line side. Both the cases have been simulated and their performances are found to be similar. Thus, it justifies that the chopper resistors in the full scale converters are sufficient to handle the low voltage fault ride through (LVRT) conditions.
Silver-Mediated Trifluoromethylation of Arenes Using TMSCF<sub>3</sub> (2011)

Capillary discharge-driven metal vapor plasma waveguides (2005)

We report the generation of dense plasma waveguides containing a large concentration of silver ions by means of a fast (approximately 55 ns first half-cycle) microcapillary discharge. Concave plasma density profiles with axial electron density > 1 x 10(19) cm(-3) were measured from discharge ablation of 330 or 440 microm diameter Ag2S capillaries with 3-5 kA peak amplitude current pulses. The dynamic of this plasma waveguide was studied with interferometry, absorption measurements, and hydrodynamic model simulations. The results are relevant to the development of efficient longitudinally pumped metal vapor soft x-ray lasers, in particular those employing transient excitation of Ni-like ions. An approach to the design of a gain saturated wave-guided 13.9 nm laser in Ni-like Ag is discussed.
