Towards an Ethical Electronics? Ecologies of Congolese Conflict Minerals

This paper asks how coltan, casseterite, wolframite and gold ores mined in the Democratic Republic of Congo relate networked microelectronics to brutal warlords, and what legal and industrial actions have been enacted by activists, NGOs, po...

Effect of physiochemical parameters on yield and biological efficiency of Volvariella volvacea cultivated on empty fruit bunch pellets

Background: Volvariella volvacea is a highly nutritious edible mushroom grown mainly in Southeast Asian countries. However, the low yield of V. volvacea has discouraged farmers from engaging in its production. Objective: The study was condu...

Computing Research on Nanoparticle Thermophoresis Deposition in Supercritical Carbon Dioxide Fluid

The movement and deposition of nanoparticles in supercritical carbon dioxide is a current international frontier subject. In the development of new nuclear reactors, using supercritical carbon dioxide Brayton cycle instead of traditional st...

Monitoring of coastal dynamics at Subang Regency using Landsat Collection Data and Cloud Computing Based

This study aims to better understand the coastal dynamics along the 6.89 km of Subang shoreline using Landsat data and GIS methods with cloud computing-based analysis. The data is processed using remote sensing techniques, image classificat...

An Evidence Theoretic Approach for Traffic Signal Intrusion Detection

The increasing attacks on traffic signals worldwide indicate the importance of intrusion detection. The existing traffic signal Intrusion Detection Systems (IDSs) that rely on inputs from connected vehicles and image analysis techniques can...

FPGA-based multi-view stereo system with flexible measurement setup

In recent years, stereoscopic image processing algorithms have gained importance for a variety of applications. To capture larger measurement volumes, multiple stereo systems are combined into a multi-view stereo (MVS) system. To reduce the...

Two lower-bounding algorithms for the p-center problem in an area

Abstract The p-center location problem in an area is an important yet very difficult problem in location science. The objective is to determine the location of p hubs within a service area so that the distance from any point in the area to ...

Characterisation of COVID-19 deaths by vaccination types and status in Malaysia between February and September 2021

Uncovering the Tradeoffs and Synergies of Ecosystem Services in Mining Landscapes: Spatiotemporal and Factor Detection Perspective

Revealing the spatial-temporal evolution and interactions of ecosystem services (ESs) in mining area is critical for sustainable environmental management. The temporal and spatial characteristics and changing trends of six ESs in Yuzhong mi...

Assessing the impact of forest structure disturbances on the arboreal movement and energetics of orangutans—An agent-based modeling approach

Agent-based models have been developed and widely employed to assess the impact of disturbances or conservation management on animal habitat use, population development, and viability. However, the direct impacts of canopy disturbance on th...

Agent-based multi-tier SLA negotiation for intercloud

Abstract The evolving intercloud enables idle resources to be traded among cloud providers to facilitate utilization optimization and to improve the cost-effectiveness of the service for cloud consumers. However, several challenges are rais...

Experience of puppet usage for managment of Tier-1 GRID cluster at NRC "Kurchatov Institute"

This article is about the organization of the cluster management using puppet. It tells about: safety of usage, from the point of view of mass apply at a computing cluster wrong configuration (by reason of human factor); collaboration work ...

Internal Decoupling in Nonlinear Process Control

A simple method has been investigated for the total or partial removal of the effect of non-linear process phenomena in multi-variable feedback control systems. The method is based upon computing the control variables which will drive the p...

Numerical mathematics and computing

Authors Ward Cheney and David Kincaid show students of science and engineering the potential computers have for solving numerical problems and give them ample opportunities to hone their skills in programming and problem solving. The text a...

Exact Solutions of Damped Improved Boussinesq Equations by Extended (G′/G)-Expansion Method

With the help of the auxiliary function method, we solved the improved Boussinesq (IBq) equation with fluid dynamic damping and the modified IBq (IMBq) equation with Stokes damping, and we obtained their three types of travelling wave exact...

Survey of Hybrid Cloud Workflow Scheduling

In the context of data explosion,traditional cloud computing is faced with the dilemma of insufficient local cloud resources and high expansion cost.However,the newly emerging hybrid cloud combining resource-rich public cloud and data-sensi...

Methods of solving of the optimal stabilization problem for stationary smooth control systems. Part I

In this article some ideas of Hamilton mechanics and differential-algebraic Geometry are used to exact definition of the potential function (Bellman-Lyapunov function) in the optimal stabilization problem of smooth finite-dimensional system...

Handbook of Mathematical Functions

The Handbook of Mathematical Functions with Formulas, Graphs, and Mathematical Tables was the culmination of a quarter century of National Bureau of Standards (NBS) work on core mathematical tools. Evaluating commonly occurring mathematical...

A game-theoretic sequential three-way decision using probabilistic rough sets and multiple levels of granularity

Abstract The sequential three-way decision accepts additional information at each level and makes more accurate definite decisions with less uncertainty. This process can also be extended to two-way classification with the finer-grained inf...
