A feasible green light assignment is an assignment of time period to each traffic stream so that only compatible traffic streams are allowed to recieve overlapping time period. In case of an intersection, it is almost always possible to find several feasible green light assignments. We usually have some goal such as to minimise the total waiting time, to maximise the volume of flow etc. , to be...

Heavy vertical traffic conditions appear in high-rise buildings especially during the rush-hour period. So, offered service provided by multi-car elevator systems for such buildings during that period is expected to work fast, efficiently and without long waiting times for users. The approach of our work focuses on reducing the passengers travel and waiting times. To do so Particle Swarm Optimi...

The distribution of times ∆t between coronal mass ejections (CMEs) in the Large Angle and Spectrometric Coronagraph (LASCO) CME catalog for the years 1996-2001 is examined. The distribution exhibits a power-law tail ∝ (∆t) with an index γ ≈ −2.36± 0.11 for large waiting times (∆t > 10 hours). The powerlaw index of the waiting-time distribution varies with the solar cycle: for the years 1996-199...

In this paper, we investigate the statistical properties of the waiting times between two successive price changes above a fixed threshold (or a fixed point) for the indices of Shanghai Stock Exchange and Shenzhen Stock Exchange. The database is from the indices of Shanghai and Shenzhen in the 10-year period from January 1997 to December 2006, and the empirical research shows that the distribut...

The effects of oestrogen deficiency-associated osteoporosis on callus distraction were investigated in rabbits. Twenty-four female New Zealand rabbits 5 to 6 months old were used. Ovariectomy was performed on 12 rabbits, which composed the osteoporotic model group. Six weeks later, osteotomy was carried out and Ilizarov external fixators were applied to the right proximal tibial metaphyses in b...

Background: Women in Somalia suffer from one of the highest maternal mortality rates world. The good utilization antenatal care (ANC) services significantly minimizes and child mortality. study aimed to identify among pregnant women Somalia. Methodology: We performed a scoping review based on York methodology. This methodology entails thorough search published academic articles, conference proc...

BACKGROUND The allocation of donor lungs for transplantation in Germany was changed on 10 December 2011 to a system based on the Lung Allocation Score (LAS). The aim of the present study is to determine whether this change has prolonged the survival of patients on the transplant waiting list and of those who have undergone lung transplantation (LTx). METHODS We retrospectively compared data f...

INTRODUCTION Surgical wait times have been shown to be of significance in other malignancies, but limited studies exist in renal cell cancer (RCC). We analyzed surgical waiting time for RCC patients to see if there was an adverse impact on pathological characteristics. METHODS Our centre triages RCC patients on the basis of perceived tumour risk. The waiting time for surgery is adjusted stage...

The literature Using the key phrases ‘healthcare’ and ‘waiting rooms’, and discounting those studies that addressed issues such as length of waiting times, the following databases were searched: CINAHL (Cumulative Index to Nursing and Allied Health Literature), Embase, Health Management Library, HMIC (Health Management Information Consortium), and PubMed. An iterative process was used to select...

Aim: To investigate the effects of pregnancy on the sexual life of Turkish women Materials and Methods: One thousand twenty six pregnant women were included in the study. The Libido Scoring System, which is a questionnaire consisting of four questions about the frequency of intercourse, the partner initiating the intercourse, orgasm and masturbation status of the pregnant women, was completed b...
