OBJECTIVE To estimate the number of deaths and readmissions associated with delay in operation after femoral fracture. DESIGN Analysis of inpatient hospital episode statistics. SETTING NHS hospital trusts in England with at least 100 admissions for fractured neck of femur during the study period. Patients People aged > or = 65 admitted from home with fractured neck of femur and discharged b...

Lung cancer is a global medical problem with a rising incidence and 5-year survival of 5%-10%. The aim of this study was to investigate whether waiting times and delays in diagnosis and treatment of patients with lung carcinoma have any bearing on prognosis and survi- val. The study was performed in the Brezovik Special Hospital for Lung Diseases and Tuberculosis. The study included all cases w...

A method is presented to divide the total congestion delay in a freeway section into six components: the delay caused by incidents, special events, lane closures, and adverse weather; the potential reduction in delay at bottlenecks that ideal ramp metering can achieve; and the remaining delay, due mainly to excess demand. The fully automated method involves two steps. First, the components of n...

In this paper, the problem of two-machine flow shop scheduling to minimize total energy costs under time-of-use tariffs is investigated. As the objective function of this study is not a regular measure, allowing intentional idle-time can be advantageous. So this study considers two approaches, one for non-delay version of the problem and the other one for a situation when inserting intentional ...

In this study, the aim was to determine the effect of 12 hours delay and time advancement of Bombyx mori larvae transfer to spinning frames on the economic traits of harvested cocoons. Our experience focused on the transfer of three lots of silkworm mature larvae to cocoon frames with 12 hours delay or advancement from usual spinning time. Commercial silkworm eggs were obtained and thr...

abstract As devices and lines shrink into the deep submicron range, the propagation delay of signals can be eeectively improved by repowering the signals using intermediate buuers placed within the routing trees. Almost no existing timing driven oorplan-ning and placement approaches consider the option of buuer insertion. As such, they may exclude solutions, particularly early in the design pro...

In this paper we present an analysis of over 236,000 file transfers between 10 widely distributed Internet hosts. The goal of this work is to broaden the understanding of how network path and congestion properties contribute to delays in TCP file transfers. The first part of our analysis investigates how end-to-end path properties (eg. physical distance, router hops, autonomous system hops, or ...

We study and solve a particular stochastic version of the Restricted Shortest Path Problem, the Stochastic Shortest Path Problem with Delay Excess Penalty. While arc costs are kept deterministic, arc delays are assumed to be normally distributed and a penalty per time unit occurs whenever the given delay constraint is not satisfied. The objective is to minimize the sum of path cost and total de...
