OBJECTIVE We aim to compare selective spinal anesthesia and general anesthesia with regard to postoperative recovery and fast-track eligibility in day surgeries. MATERIALS AND METHOD Sixty geriatric outpatient cases, with ASA II-III physical status and requiring short-duration transurethral intervention, were enrolled in the study. The cases were split into 2 groups: as general anesthesia (Gr...

Background: Female sterilization is one of the most popular methods permanent contraception for women who have completed their families. Tubectomy during caesarean section and tubal either laparoscopically or by minilaparotomy are favoured in developing countries. The aim current study was to assess incidence, details procedure complications various techniques tubectomy among at our tertiary in...

We propose a cooperative Multi-agent knowledge management system to manage patent documents and support the invention process based on the patent document analysis. It helps industrial knowledge managers to retrieve and analyze existing patent documents and extract tacit knowledge from patent documents with the aid of ontology and natural language processing techniques. It allows the invention ...

Meta-heuristics are methods that sit on top of local search algorithms. They perform the function of avoiding or escaping a local optimum and/or premature convergence. The aim of this paper is to survey, compare and contrast meta-heuristics for local search. First, we present the technique of local search (or hill climbing as it is sometimes known). We then present a table displaying the attrib...

In this paper three optimization heuristics are presented which can be utilized in attacks on the transposition cipher. These heuristics are simulated annealing, genetic algorithm and tabu search. We will show that each of these heuristics provides effective automated techniques for the cryptanalysis of the ciphertext. The property which make this cipher vulnerable, is that it is not sophistica...

This paper focuses on efficient methods for pruning the state space in cost-optimal planning. The use of heuristics to guide search and prune irrelevant branches has been widely and successfully explored. However, heuristic computation at every node in the search space is expensive, and even near perfect heuristics still leave a large portion of the search space to be explored [9]. Using up-fro...

The development of informative, admissible heuristics for cost-optimal planning remains a significant challenge in domain-independent planning research. Two techniques are commonly used to try to improve heuristic estimates. The first is disjunction: taking the maximum across several heuristic values. The second is the use of additive techniques, taking the sum of the heuristic values from a se...

BACKGROUND Many of the reproductive decisions that humans make happen without much planning or forethought, arising instead through the use of simple choice rules or heuristics that involve relatively little information and processing. Nonetheless, these heuristic-guided decisions are typically beneficial, owing to humans’ ecological rationality – the evolved fit between our constrained decisio...
