PM10 Prediction Model by Support Vector Regression Based on Particle Swarm Optimization

This paper proposes a prediction model for the PM10 forecasting in Bangkok. Particulate matter (PM10) with aerodynamic diameter up to 10 m (PM10) is targeted because these small particles effects people’s health and it constitutes major conSubscript textcern for the air quality of Bangkok. Support vector regression (SVR) has been successfully employed to solve regression problem of nonlinearity. The determination for hyper-parameters including kernel parameters and the regularization is important to the performance of SVR. Particle swarm optimization (PSO) is a method for finding a solution of stochastic global optimizer based on swarm intelligence. Using the interaction of particles, PSO searches the solution space intelligently and finds out the best one. Thus, the proposed forecasting model based on the global optimization of PSO and local accurate searching of SVR is applied to forecast PM10 in this paper. The results of this research show the practical prediction model of PM10 based on PSO-SVR is established with C = 5009, ε = 0.0011, σ = 0.1072. The mean squared error (MSE) of the prediction model using PSO-SVR is about 8.654610-11. Practical results indicate that the application of the PSO-SVR method to temperature forecasting of PM10 is feasible and effective. The results show that the model is effective and highly accurate in the forecasting of PM10.
TROPHIC INTERACTIONS OF THE FISH COMMUNITIES IN CIRATA RESERVOIR, WEST JAVA

The utilization of food resources by the fish communities in the Cirata Reservoir depends on the environmental conditions of the reservoir. Eutrophication and the presence of potentially invasive alien fishes could affect the trophic interactions of food utilization by the fish communities in the Cirata reservoir. This study aimed to analyze the trophic interactions of the fish communities in the Cirata Reservoir, West Java. The samplings were conducted in October, December 2018, and April 2019. The fish samples were collected using experimental gill nets with different mesh sizes. The stomach contents were dissected to study their food habits under a stereoscopic microscope. Data analysis was performed using the index of preponderance, niche breadth, trophic level, and index Schoener. A total of 21 species of fishes in the Cirata Reservoir utilized food resources, including phytoplankton, zooplankton, aquatic plants/macrophytes, molluscs, insects (adult and larvae), worms, a body part of fishes and crustaceans, pellets and detritus. The fish communities had a wide range of niche between 0.00-0.32 and trophic levels between 2.00-3.63. The non-native fishes in the Cirata Reservoir had the food overlapping potential with native fishes, from low to high categories, especially from the Cichlidae. Trophic interaction of fish communities in the Cirata reservoir was still relatively stable, characterized by overlapping food niche in the low to medium categories. The fish stock enhancement effort such as fish introduction or restocking in the Cirata Reservoir could still be carried out with a precautionary approach to filling empty niches and avoiding the potential for invasive alien fish species.
Review Article: Global Monitoring of Snow Water Equivalent using High Frequency Radar Remote Sensing

Abstract. Seasonal snow cover is the largest single component of the cryosphere in areal extent, covering an average of 46 million square km of Earth's surface (31 % of the land area) each year, and is thus an important expression of and driver of the Earth’s climate. In recent years, Northern Hemisphere spring snow cover has been declining at about the same rate (~ −13 %/decade) as Arctic summer sea ice. More than one-sixth of the world’s population relies on seasonal snowpack and glaciers for a water supply that is likely to decrease this century. Snow is also a critical component of Earth’s cold regions' ecosystems, in which wildlife, vegetation, and snow are strongly interconnected. Snow water equivalent (SWE) describes the quantity of snow stored on the land surface and is of fundamental importance to water, energy, and geochemical cycles. Quality global SWE estimates are lacking. Given the vast seasonal extent combined with the spatially variable nature of snow distribution at regional and local scales, surface observations will not be able to provide sufficient SWE information. Satellite observations presently cannot provide SWE information at the spatial and temporal resolutions required to address science and high socio-economic value applications such as water resource management and streamflow forecasting. In this paper, we review the potential contribution of X- and Ku-Band Synthetic Aperture Radar (SAR) for global monitoring of SWE. We describe radar interactions with snow-covered landscapes, characterization of snowpack properties using radar measurements, and refinement of retrieval algorithms via synergy with other microwave remote sensing approaches. SAR can image the surface during both day and night regardless of cloud cover, allowing high-frequency revisit at high spatial resolution as demonstrated by missions such as Sentinel-1. The physical basis for estimating SWE from X- and Ku-band radar measurements at local scales is volume scattering by millimetre-scale snow grains. Inference of global snow properties from SAR requires an interdisciplinary approach based on field observations of snow microstructure, physical snow modelling, electromagnetic theory, and retrieval strategies over a range of scales. New field measurement capabilities have enabled significant advances in understanding snow microstructure such as grain size, densities, and layering. We describe radar interactions with snow-covered landscapes, the characterization of snowpack properties using radar measurements, and the refinement of retrieval algorithms via synergy with other microwave remote sensing approaches. This review serves to inform the broader snow research, monitoring, and applications communities on progress made in recent decades, and sets the stage for a new era in SWE remote-sensing from SAR measurements.
Motion Analysis of a Robotic Assisted Surgery and Microsurgery System - Experimental Verification

Motion analysis of a parallel robot assisted minimally invasive surgery/microsurgery system (PRAMiSS) and the control structures enabling it to achieve milli/micromanipulations under the constraint of moving through a fixed penetration point or so-called remote centre-of-motion (RCM) are presented in this article. Two control algorithms are proposed suitable for minimally invasive surgery (MIS) with submillimeter accuracy and for minimally invasive micro-surgery (MIMS) with submicrometer accuracy. The RCM constraint is performed without having any mechanical constraint. Control algorithms also apply orientation constraint preventing the tip to orient relative to the soft tissues due to the robot movements. Experiments were conducted to verify accuracy and effectiveness of the proposed control algorithms for MIS and MIMS operations. The experimental results demonstrate accuracy and performance of the proposed position control algorithms.
R&D/marketing communication during the fuzzy front-end

The planning stage of an innovation project has a great effect on the commercial performance of the project. During the "fuzzy front-end", the organization formulates a concept of the product to be developed, and determines whether or not the organization will invest resources in the concrete development of the idea. The integration of R&D and marketing activities is a necessary condition for success in innovation projects. The research question of this study is: from an information processing perspective, what role does information transfer play in integrating R&D and marketing functions during the planning stage, and what effects do project formalization and project centralization of R&D and marketing planning activities have on the efficiency of marketing and technological uncertainty reduction? The authors use an ex post facto research design to test the propositional model. The findings show that successful project teams are characterized by a maximum uncertainty reduction during planning, i.e., by a maximum decrease of R&D and marketing task variability, and a maximum increase of R&D and marketing task analyzability. Information flows between these functions help them to achieve this efficient uncertainty reduction. While project centralization has a negative effect on efficient uncertainty reduction, project formalization is curvilinearly related to the amount of uncertainty reduced during planning. >
Full-Scale Measurements on Board PSRV S.A.Agulhas II in the Baltic Sea

The presence of rich natural resources in Arctic waters continuously raises interest in marine operations in ice. Despite the availability of several full-scale measurements in ice-infested waters, knowledge of the impact of ice-structure interaction on the ship’s hull and propulsion system as well as on the comfort of the crew and passengers on board is limited. This can be attributed to: (1) the fact that the effects of ice loading on the ship hull has not yet been related to prevailing ice conditions, (2) ice loading and the related response of the propulsion system is an almost unknown process and (3) vibration levels resulting from ship-ice interaction are not known. To increase the knowledge in these fields, full-scale measurements were conducted on the PSRV (Polar Supply and Research Vessel) S.A. Agulhas II in the Baltic Sea during March 2012. Measurements on the following were obtained: (1) ice loads on the ship hull and propulsion system, (2) ice-induced structural vibration and noise, (3) whole-body vibration comfort, (4) ship dynamics in ice, (5) global ice loads, (6) underwater noise and (7) mechanical and physical sea ice properties. Furthermore, the effect of ship operations on the loads induced by ice on the ship hull was studied during a variety of ship maneuvers. This paper focuses on selected aspects of the conducted full-scale measurements, including: (1) the ice loading on the ship hull and propulsion system, (2) human comfort on board (3) mechanical ice property measurements, (4) the effect of ship operations on the maximum ice loads on different hull areas, (5) the natural frequencies and damping effects of the propeller shaft and (6) the possibility of the resonance of the propeller shaft’s due to the sequential propeller blade impacts with ice.
TIGR Assembler: A New Tool for Assembling Large Shotgun Sequencing Projects

ABSTRACT A new approach to assembling large, random shotgun sequencing projects has been developed. The TIGR Assembler overcomes several major obstacles to assembling such projects: the large number of pairwise comparisons required, the presence of repeat regions, chimeras introduced in the cloning process, and sequencing errors. A fast initial comparison of fragments based on oligonucleotide content is used to eliminate the need for a more sensitive comparison between most fragment pairs, thus greatly reducing computer search time. Potential repeat regions are recognized by determining which fragments have more potential overlaps than expected given a random distribution of fragments. Repeat regions are dealt with by increasing the match criteria stringency and by assembling these regions last so that maximum information from nonrepeat regions can be used. The algorithm also incorporates a number of constraints, such as clone length and the placement of sequences from the opposite ends of a clone. TIGR A.
Applying Vision-Based Pose Estimation in a Telerehabilitation Application

In this paper, an augmented reality mirror application using vision-based human pose detection based on vision-based pose detection called ExerCam is presented. ExerCam does not need any special controllers or sensors for its operation, as it works with a simple RGB camera (webcam type), which makes the application totally accessible and low cost. This application also has a system for managing patients, tasks and games via the web, with which a therapist can manage their patients in a ubiquitous and totally remote way. As a final conclusion of the article, it can be inferred that the application developed is viable as a telerehabilitation tool, as it has the resource of a task mode for the calculation of the range of motion (ROM) and, on the other hand, a game mode to encourage patients to improve their performance during the therapy, with positive results obtained in this aspect.
‘Otherworldliness’: The Pull of Black Velvet, Latex, Tights, Quilts, Tablecloths, and Frocks: An Interview with Will Alsop

Will Alsop is most immediately identified with the expressive, colourful and painterly in architecture. His reputation as architecture's masterly Abstract Expressionist all too easily overshadows his engagement with more specific material and conceptual concerns. In conversation with Alsop at his Battersea studios, Mark Garcia discovered that a preoccupation with textiles has been latent in his work since his studies at the Architectural Association (AA) in the early 1970s. It is only, however, in a recent body of work that Alsop has started to innovatively bring it to the fore by translating the unexploited qualities of textiles into a plausible architecture.

Management strategy for SmartGrid : a cluster system analysis method

Recently, Distributed Generation (DG) technologies become more potential in electricity supply contributors to electric utilities. It leads to increase the grid integration ratio of DG. Thus, the trend of decentralized power systems has been considered as a future of energy supply systems. According to this fact, the distribution systems must be changed from a passive control area to be an active control area. To overcome and realize this issue, the clustering power systems approach is developed. The main idea of this concept is to coexist the DG with the conventional power systems. Therefore, the system structure and the control approach are introduced and developed based on the conventional system. The cluster network structure keeps the main idea of conventional interconnected grid. Consequently, the clustering power systems concept intends to cluster the power systems into several areas, called cluster area. As a direct result, the cluster network structure can be described like the interconnected grids. In order to empower and turn the ordinary passive distribution system to be the active system, the clustering approach announces the distribution management system (DMS) for the cluster automation application. The DMS application is the cluster controller and management, which applies in each cluster area. To accomplish the DMS functionality, control functions based on cluster concept have been developed continuously, e.g. the multi-level clusters control approach. Besides the development of cluster control approach, a cluster analysis strategy is cautiously considered as well, since it is a key to complete a cluster management and an optimization process. A hybrid calculation technique is consequently proposed to be a solution for cluster analysis, because it offers a possibility to integrate a character of interconnected clusters into the analysis. Hence, the cluster analysis can be employed in a decoupling way. To evolve the cluster analysis, a character of distribution network has to be taken into account. The character of distribution network is dominated by the unbalanced condition e.g. multi-phase feeder system. Moreover, the penetration of DG units can cause unbalanced condition as well, e.g. single phase feed in of home PV systems. To deal with unbalanced condition, an asymmetrical sequence hybrid and asymmetrical three-phase fourwire hybrid analysis method is rolled out, both are developed based on a difference issue of load flow studies. All in all, the cluster analysis is a key to execute optimization and management process of cluster system operation as well as the supervisory of automated cluster control application. Finally, the proposed hybrid analysis is ready to be the main function in order to ensure and forwards the development of clustering power systems philosophy to be one of the best solutions for the future smart gird applications.
Making Fast Food: From the Frying Pan into the Fryer

The flourishing fast food industry represents one particular blueprint of how to live. Reiter analyses the profound consequences of this blueprint for many spheres of life: women's work, youth employment, the labour movement, the family, and the community. Since the 1970s young people and women have increasingly entered the job market in low waged, service-sector jobs. Family life, she explains, has changed dramatically in the last forty years as many activities that were traditionally part of the home have been replaced by services available in the marketplace. The production of meals and those who produce them have moved from the family kitchen to the highly regulated corporate workplace where workers are like the interchangeable parts of a machine.
Fatigue tests and numerical analyses of the PAWO autonomous electric vehicle

The following article presents fatigue testing and FEM numerical analysis of an autonomous electric vehicle, PAWO autonomous operational support platform. The purpose of the study, which was carried out in the ŁUKASIEWICZ – Automotive Industry Institute, was to verify the structure of the platform by forcing in three axes on the position: a table with six degrees of freedom "MAST", as well as conducting fatigue numerical analyses, allowing to determine places critical for fatigue endurance. This will be the starting point for the modification of the structure, and also will allow you to identify places that you need to pay attention to during tests and subsequent operation. The results of these tests allow us to determine critical places due to fatigue strength and possible intervention before starting field tests with a complete vehicle, as well as to detect places that should be noted during tests, inspections and tests, and in development versions of the vehicle.
The Choice of a Solid Waste Management System Using the Electre Ii Decision-Aid Method

A multicriteria decision-aid method, Electre II, was applied to the real choice process of a solid waste management system in the Uusimaa region, Finland. The criteria used were chosen by a supervision group. The weights of the criteria were defined by the managers of environmental and technical affairs of each municipality in Uusimaa, Finland. The use of the Electre II method leads us to recommend centralized incineration as the best municipal solid waste management system for the planning region. However, the second best alternative, intermediate RDF combustion with intermediate landfilling was finally chosen by the municipalities.

iProbe-d: a hot-carrier and oxide reliability simulator

In this paper we describe a hot-carrier and oxide reliability simulator, iProbe-d. In this program, a probabilistic timing approach is employed to find the most susceptible devices to hot-carrier degradation and/or oxide breakdown in a CMOS VLSI digital circuit design under expected operating conditions. After the damage in each device is determined, a combination of damaged-transistor model, RC delay and critical path analysis is used to estimate the impact of hot-carrier effects (HCE) on circuit performance; namely, the increase of circuit delay. The results can then be used to improve the reliability of the circuit prior to fabrication. <<ETX>>
Natural balancing mechanisms in converters

Natural Balancing Mechanisms in Converters J.W. van der Merwe Department of Electric and Electronic Engineering University of Stellenbosch Private Bag X1, 7602 Matieland, South Africa Dissertation: PhD(Eng) (E&E) March 2011 This thesis investigates the natural balancing mechanisms in multilevel and modular converters using phase shifted carrier pulse width modulation. Two groups of mechanisms are identified; a weak balancing mechanism that is only present when the switching functions are interleaved and a strong mechanism that occurs irrespective of the interleaving of the switching functions. It is further shown that the strong balancing mechanism can be divided into a balancing mechanism that depends on the direct exchange of unbalance energy and a loss based balancing mechanism. Each of the mechanisms is discussed and analysed using a converter where the specific mechanism dominates as example. Emphasis is placed on the calculation of the rebalancing time constant following a perturbation. Closed form expressions for the rebalancing time constants for each of the analysed converters are presented.
