We investigated the utility of the Cambridge Behavioural Inventory (CBI), a carer-completed questionnaire, in a large cohort with Parkinson's disease (PD) (n = 215). In a sub-cohort of 112 patients with PD, the CBI was found to be a valid instrument compared with the Neuropsychiatric Inventory, PDQ-39 and UPDRS, with high internal consistency. Furthermore,… (More)
Electronic commerce and associated business-to-business transaction capabilities have changed the way in which the supply chain operates. The Internet has enabled information exchange on an unprecedented scale, often at a pace too fast for normal consumption. Companies are not equipped to make effective use of data from warehouse and transportation… (More)
In this research, we model a semiconductor wafer fabrication process as a complex job shop, and adapt a Modified Shifting Bottleneck Heuristic (MSBH) to facilitate the multi-criteria optimization of makespan, cycle time, and total weighted tardiness using a desirability function. The desirability function is implemented at two different levels of the MSBH:… (More)
The standard unit of transfer in new semiconductor wafer fabrication facilities is the front opening unified pod (FOUP). Due to automated material handling system and cost concerns, the number of FOUPs in a wafer fab is kept limited. Large 300-mm wafers allow for customer orders to be filled with less than a full FOUP of wafers in these new fabs, thereby… (More)
The Research Laboratory of Electronics is an interdepartmental laboratory in which faculty members and graduate students from numerous academic departments conduct research.
A linear transistor model (or other linear two-terminal-pair device) is imbedded in a lossless passive network N and the properties of the complete system, as measured at two specified terminal pairs, are described by the open-circuit impedances Zll 1 Z12' Z21, Z22' The quantity IZ 2 1-Z1212 U 4(RllR22-R12R21) where Rjk is the real part of Zjk is defined as… (More)
BACKGROUND Infection with Helicobacter pylori is the main cause of peptic-ulcer disease. Treatment of this infection might lower the prevalence of dyspepsia in the community and improve quality of life. We investigated this possibility in a double-blind randomised controlled trial. METHODS Individuals aged 40-49 years were randomly selected from the lists… (More)
