Human System Modeling for Optimum Labor Utilization and Man-Machine Configuration

Manufacturing organization with increased in the organizational complexity, is facing difficulty in measuring its performance. Various factors could affect manufacturing performance such as equipment performance, material planning and human resources. In this paper, focus was given primarily on the human resource which was considered as an important factor of the simulation model development to achieve optimum utilization and ensure efficient operator allocation to the machines. Static modeling was performed to capture all the critical factors contributing to the work such as the operator activity sequence, the time value for each activity and also the machine process time for each batch of product. A dynamic model was then developed to enable quantitative analysis in the optimization of human system performance. This paper illustrates the application of different modeling approaches to demonstrate advantages gained in the process of evaluating human system performance

Preliminary investigations of the endoparasite component communities of stray cats from Kuala Lumpur

Investigations into the endoparasite fauna of stray cats from Kuala Lumpur were carried out to determine the present population and diversity. Post-mortem examinations of selected organ from 85 cats revealed that 87.1% cats harbored endoparasites, with an average of 36.65 worms per infected cat. Endoparasite recovered consists of five nematode species (Toxocara catti, Toxocara malayensis, Ancylostoma ceylanicum, Ancylostoma braziiiensie and Strongyloides sp.), two cestode species (Dipylidium caninum and Taenia taeniaformis) and one trematode species (Platynosomum fastosum). Toxocara sp. was shown to have the highest prevalence and mean intensity values. Present observations provided additional insights to the environment, behavior and diet of the local strays. Ancylostoma ceylanicum, Ancylostoma broziliensie, Toxocara catti and Dipylidium caninum are known to be of medical significance

Ectoparasites of murids in peninsular Malaysia and their associated diseases

A considerable number of rat-borne ectoparasite studies have been conducted since the early 1930s in the Malayan Peninsula (now known as peninsular Malaysia). The majority of studies were field surveys and collections of specimens across the region, and were conducted primarily to catalogue the ectoparasite host distribution and discover novel species. This has generated a signification amount of information, particularly on the diversity and host distribution; other aspects such as morphology, host distribution and medical significance have also been investigated. Amongst the four main groups (mites, fleas, ticks, lice), rat-borne mites have received the most attention with a particular emphasis on chiggers, due to their medical importance. More recent studies have examined the distribution of ectoparasites in rats from different habitat type simplicating a high prevalence of zoonotic species infesting rat populations. Despite being capable of transmitting dangerous pathogens to human, the health risks of rat-borne ectoparasites appear to be small with no serious outbreaks of diseases recorded. Although an extensive number of works have been published, there remain gaps in knowledge that need to be addressed, such as, the distribution of under studied ectoparasite groups (listrophorids and myobiids), determining factors influencing infestation, and understanding changes to the population distribution over time

Measurement of the polarisation of W bosons produced with large transverse momentum in pp collisions at sqrt(s) = 7 TeV with the ATLAS experiment

This paper describes an analysis of the angular distribution of W->enu and W->munu decays, using data from pp collisions at sqrt(s) = 7 TeV recorded with the ATLAS detector at the LHC in 2010, corresponding to an integrated luminosity of about 35 pb^-1. Using the decay lepton transverse momentum and the missing transverse energy, the W decay angular distribution projected onto the transverse plane is obtained and analysed in terms of helicity fractions f0, fL and fR over two ranges of W transverse momentum (ptw): 35 < ptw < 50 GeV and ptw > 50 GeV. Good agreement is found with theoretical predictions. For ptw > 50 GeV, the values of f0 and fL-fR, averaged over charge and lepton flavour, are measured to be : f0 = 0.127 +/- 0.030 +/- 0.108 and fL-fR = 0.252 +/- 0.017 +/- 0.030, where the first uncertainties are statistical, and the second include all systematic effects.Comment: 19 pages plus author list (34 pages total), 9 figures, 11 tables, revised author list, matches European Journal of Physics C versio

Observation of a new chi_b state in radiative transitions to Upsilon(1S) and Upsilon(2S) at ATLAS

The chi_b(nP) quarkonium states are produced in proton-proton collisions at the Large Hadron Collider (LHC) at sqrt(s) = 7 TeV and recorded by the ATLAS detector. Using a data sample corresponding to an integrated luminosity of 4.4 fb^-1, these states are reconstructed through their radiative decays to Upsilon(1S,2S) with Upsilon->mu+mu-. In addition to the mass peaks corresponding to the decay modes chi_b(1P,2P)->Upsilon(1S)gamma, a new structure centered at a mass of 10.530+/-0.005 (stat.)+/-0.009 (syst.) GeV is also observed, in both the Upsilon(1S)gamma and Upsilon(2S)gamma decay modes. This is interpreted as the chi_b(3P) system.Comment: 5 pages plus author list (18 pages total), 2 figures, 1 table, corrected author list, matches final version in Physical Review Letter
