Given a product design and a repair network, a level of repair analysis (LORA) determines for each component in the product (1) whether it should be discarded or repaired upon failure and (2) at which echelon in the repair network to do this. The objective of the LORA is to minimize the total (variable and fixed) costs. We propose an IP model that generalizes the existing models, based on cases...

The antioxidant effect of a trihydroxyflavone extract from Scutellaria baicalensis on oxidation induced by ultraviolet light, was studied with phosphatidylcholine liposome membrane. Also, as standards, the antioxidative activity of baicalin, wogonin, baicalein and butylated hydroxytoluene (BHT) was investigated. Comparison of the protective effects of the compounds studied against photoinduced ...

OBJECTIVE Scutellaria (Lamiaceae) has been implicated for medicinal purposes both in modern and traditional medicine. Some species of the genus Scutellaria has extensively been studied for anticancer activity. Scutellaria luteo-coerulea (S. luteo-coerulea) is one of the Iranian species of the genus Scutellaria. MATERIALS AND METHODS In the present study, cytotoxic and apoptogenic properties o...

There is growing interest in the Internet of Things (IoT) and especially Low-Power Wide Area Networks (LPWAN), which are rapidly being rolled-out globally. Within the LPWAN market, LoRaWAN is considered a leading solution which has achieved significant success. Despite the rapid uptake of LoRaWAN, scalability concerns arising from interference and contention are also growing. While the current ...

Reasoning About Rational Agents is concerned with developing practical reasoning (as contrasted with theoretical reasoning) for rational computer agents within the “Belief, Desire, Intention” model. The BDI model for computer agents is based on the theory of rational action in humans put forward in 1988 by the philosopher M. Bratman in his book Intention, Plans and Practical Reason. BDI logics ...

Long Range (LoRa) is a popular technology used to construct Low-Power Wide-Area Network (LPWAN) networks. Given the popularity of LoRa it is likely that multiple independent LoRa networks are deployed in close proximity. In this situation, neighbouring networks interfere and methods have to be found to combat this interference. In this paper we investigate the use of directional antennae and th...

Level of Repair Analysis (LORA) is a prescribed procedure for defence logistics support planning. For a complex engineering system containing perhaps thousands of assemblies, sub-assemblies, components, etc. organized into several levels of indenture and with a number of possible repair decisions, LORA seeks to determine an optimal provision of repair and maintenance facilities to minimize over...

The level of repair analysis (lora) gives answers to three questions that are posed when deciding on how to maintain capital goods: 1) which components to repair upon failure and which to discard, 2) at which locations in the repair network to perform each type of repairs, and 3) at which locations in the network to deploy resources, such as test equipment. The goal is to achieve the lowest pos...

We present our proposed algorithm in this paper, a reactive Location Routing Algorithm with Directional ClusterBased Flooding (LORA-DCBF) for inter-vehicle communication in the context of optimizing traffic flow and increasing vehicular safety. We consider the performance and motorway environment with associated high mobility in highway and compare LORADCBF with Location Routing Algorithm with ...
