A kilowatt-class pulsed carbon dioxide laser radar system was recently installed at the top of Mount Haleakala (see Figure 1) at the Maui Space Surveillance Site (MSSS). The four-year Field Ladar Demonstration (FLD) program was awarded to Textron Systems Corporation (TSC) and contracted through the United States Army Strategic Missile and Defense Command (USASMDC). The work was completed in 199...

The Universal Mobile Telecommunications System (UMTS) will provide multimedia services to users in whatever environment via uniform service access procedures. Efficient Medium Access Control (MAC) protocols are needed to guarantee high capacity. This paper deals with Packet Reservation Multiple Access (PRMA), an efficient MAC protocol that has been widely studied in terrestrial microcellular sy...

Scenario-based modeling in live sequence charts (LSC) involves specifying multi-modal inter-object scenarios, in which events can be mandatory (hot) or possible (cold). In translating LSCs into automata over infinite words, an intermediate step constructs a kind of transition system that we call a modal state structure (MSS). Here we present MSSs as abstract forms of modal scenarios (with both ...

The aim of this study was to test the hypothesis in the literature that torque resistance of parkinsonian rigidity is the difference between the independent contributions of stretched and shortened muscles. The hypothesis was tested using muscle-specific stretch-shortening (MSSS) EMG ratio in this study. Nineteen patients with idiopathic Parkinson's disease (PD) and 18 healthy subjects (the mea...

The aim of this study was to evaluate the effect of ergonomic workstation design on musculoskeletal risk factors (MRFs) and musculoskeletal symptoms (MSSs) reduction among female semiconductor fabrication room (fab) worker. A prospective study was conducted to follow up 40 female fab workers over 3 months after intervention. The intervention program focused on reducing shoulder loadings for 20 ...

OBJECTIVE To define whether minor adult hemoglobin A2 (HbA2, α2δ2) exerts any protective activity in multiple sclerosis (MS). METHODS HbA2 levels were measured in 146 MS patients with high performance liquid chromatography and association with MS Severity Scores (MSSS) were determined. HbA2 associations with blood count parameters were also studied using blood counts evaluated on the same day...

In Multiple Sclerosis (MS) the relationship between disease process in normal-appearing white matter (NAWM) and the development of white matter lesions is not well understood. In this study we used single voxel proton 'Quantitative Magnetic Resonance Spectroscopy' (qMRS) to characterize the NAWM and thalamus both in atypical 'Clinically Definite MS' (CDMS) patients, MRI(neg) (N = 15) with very ...

abstract aim and background: the purpose of the present study was to examine the psychometric properties of multiple sclerosis self-efficacy scale (msss) in a sample population of iranian patients. methods and materials: this research is a descriptive-correlational study with a population of patients afflicted with ms from north khorasan and hamedan provinces. a number of 120 patients, who had ...

BACKGROUND The Multiple Sclerosis Severity Score (MSSS) is obtained by normalising the Expanded Disability Status Scale (EDSS) score for disease duration and has been a valuable tool in cross-sectional studies. OBJECTIVE To assess whether use of age rather than the inherently ambiguous disease duration was a feasible approach. METHOD We pooled disability data from three population-based coh...
