در این پژوهش ساخت خمیر کاغذ سولفیت قلیایی قابل رنگ بری از الیاف کارتن کنگرهای کهنه بررسی شده است. متغیرهای خمیر کاغذسازی شامل سه مقدار قلیاییت فعال (14، 16 و 18 درصد وزن خشک ماده اولیه و بر مبنای na2o)، دو نسبت سولفیت سدیم به هیدروکسید سدیم (50:50 و 70:30)، چهار دمای پخت (125، 145، 165 و 175 درجه سانتیگراد) و دو زمان پخت (60 و 120 دقیقه) مورد مطالعه قرار گرفته است. پس از انجام تیمارهای آزما...
Multi-pattern matching with wildcards is to find all the occurrences of a set of patterns with wildcards in a text. This problem arises in various fields, such as computational biology and network security. But the problem is not extensively studied as the single pattern case and there is no efficient algorithm for this problem. In this paper, we present efficient algorithms based on the fast F...
Sperm chemotaxis in mammals have been identified towards several female sources as follicular fluid (FF), oviduct fluid, and conditioned medium from the cumulus oophorus (CU) and the oocyte (O). Though several substances were confirmed as sperm chemoattractant, Progesterone (P) seems to be the best chemoattractant candidate, because: 1) spermatozoa express a cell surface P receptor, 2) capacita...
Given a string S, the compressed indexing problem is to preprocess S into a compressed representation that supports fast substring queries. The goal is to use little space relative to the compressed size of S while supporting fast queries. We present a compressed index based on the Lempel–Ziv 1977 compression scheme. We obtain the following time-space trade-offs: For constant-sized alphabets (i...
ÐAfter a ªboomº period from the late 80s to the early 90s, there appears to have been a reduction in the amount of work published on Concurrency Control (CC) in real-time database systems (RTDBS) in general and firm RTDBS in particular. This may be because existing paradigms (e.g., Optimistic CC) have been pushed to their limits and it is difficult to extract additional meaningful performance. ...
Human papillomavirus (HPV) infections are deemed to play a role in the pathogenesis of oral cavity cancer (OCC). However, their exact prevalence and clinical significance remain unclear. Herein, we investigated the prevalence and prognostic value of HPV infections in a large sample of Taiwanese OCC patients.This study was designed as a retrospective cohort study. Between 2004 and 2011, we ident...
The performance of high-volume transaction processing systems is determined by the degree of hardware and data contention. This is especially a problem in the case of distributed systems with glob~! transactions accessing and updating objects from multiple systems. While the conventional two-phase locking method 11f centralized systems can be adapted for concurrency control in distributed syste...
The Health Protection Agency (HPA) (currently Public Health England) implemented the Health Protection Event-Based Surveillance (EBS) to provide additional national epidemic intelligence for the 2012 London Olympic and Paralympic Games (the Games). We describe EBS and evaluate the system attributes. EBS aimed at identifying, assessing and reporting to the HPA Olympic Coordination Centre (OCC) p...
In the recent times many accessible congestion control procedures have no capability to differentiate involving two major problems like packet loss by link crash and packet loss by congestion due to buffer overflow. Consequently these resolutions effect in form of wastage of possessions because they target only on the packet drop by link crash that has the unnecessary importance. Consumption of...
In this paper, we introduce an novel emotional agent system in 3D virtual world based on OCC (Ortony, Clore and Collins) theory, FCM (Fuzzy Cognitive Map) and GoalNet. The agent system is designed based on Goal Net model. Emotional modeling and decision making are based on OCC and FCM inference. Emotions modeled by the OCC model are incorporated into FCM inference. It has been shown emotion has...
