In dynamic networks each arc is weighted with a capacity and a transit time. The former is the maximum amount of flow that can travel through the arc per unit time, the later is the time period needed for flow to travel through the arc. In this article, an additional weight operation probability, is assigned to each arc to note the capability of the arc's successful transition. The performance of dynamic networks is defined by the probability that the maximum dynamic flow from source to sink within required time horizon is no less than specified threshold. To the best of our knowledge, no existing article had considered dynamic flow and network reliability simultaneously. Based on facts that there is always a maximum dynamic flow among the temporally repeated flows and the maximum temporally repeated flow can be obtained via an equivalent minimum cost maximum flow problem, we present a pioneering algorithm to compute performance of dynamic networks by solving minimum cost maximum flow and two-terminal capacity reliability at the same time.","PeriodicalId":405664,"journal":{"name":"2018 3rd International Conference on Computer and Communication Systems (ICCCS)","volume":"19 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134346289","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

They present one of the most rampant problems in Philippine transportation, and current systems designed to detect colorum vehicles include only manual visual inspection which are prone to error and can disrupt traffic. An RF-based (Radio Frequency) system for automatically detecting registered vehicles was designed and tested to solve this problem. This system uses a pair of RF nodes - one installed in a PUV to mark it as registered and one installed in a base station to detect RF nodes in passing PUVs. Test results showed that it was possible to detect a registered PUV 100% of the time when the system is deployed at a PUV stop, and 97% of the time when deployed along an open road in a PUV route. Detection distances for registered PUVs were also measured to be at an average of 77m for base stations deployed at waiting sheds, which would grant traffic enforcers enough time to flag down a suspected colorum vehicle. Overall, the system can reduce the number of instances that traffic enforcers would have to flag down and inspect vehicles, therefore resulting in a more efficient implementation of traffic rules.","PeriodicalId":405664,"journal":{"name":"2018 3rd International Conference on Computer and Communication Systems (ICCCS)","volume":"9 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133958724","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This paper hence considers the model of distributed spectrum sensing. In addition, this paper focuses on the hybrid strategy, which combines the underlay and interweave approaches. This paper also considers the scenario, in which each SU is in the presence of co-channel interference when performing distributed spectrum sensing and data transmission. Based on the conducted performance analysis of the considered distributed model, this paper studies the transmit power allocation problem for the distributed spectrum sensing network. The power allocation problems have also been extensively studied in the literature. However, most of them are discussed in the scenario of underlay spectrum-sharing networks. As opposed to the existing works, this paper considers the power allocation problem in the hybrid paradigm and the scenario, in which the received signal at each SU is in the presence of co-channel interference. We formulate our power allocation problem as an optimization problem. The optimization problem is to seek the best power allocation scheme to maximize the throughput of secondary network while satisfying the total transmit power budget and the target SINR constraint of the primary network. The person by person optimization (PBPO) approach is used to solve the above optimization problem. Our results confirm that the proposed optimal power allocation scheme outperforms the uniform power allocation scheme.","PeriodicalId":405664,"journal":{"name":"2018 3rd International Conference on Computer and Communication Systems (ICCCS)","volume":"24 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126979824","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

There are different kinds of measuring light and these are the LUX meter, Quantum Meters, Electrical Light meter and other kinds of sensor that measures light. One of these is the Photosynthetic Active Radiation (PAR). Studies show that the light in forest canopies typically requires a huge quantity of light sensors. Some of these light sensors usually require huge amount of money, hence, detailed studies for this agricultural used are very expensive. This study shows the creation and testing of a practical and inexpensive sensor for measuring photo-synthetic photon flux density or PAR. Detailed instructions are provided for assembly and calibration. The sensor was made from a blue enhanced silicon photodiode held within an 8mm substrate protective casing coated with IR blocking filter. The Apogee SQ-520 Quantum Sensor was used as a standard for comparison. The stability of the VTB8440BH sensor compared favourably to Apogee SQ-420 Quantum Sensor. Based on the data gathered, the group was able to obtain the linearity of the proposed and commercially PAR sensors which has a correlation coefficient of 0.99. This means that it is close to +1, thus, it has a positive correlation coefficient. The group was able to meet and satisfy all of the required objectives stated in the paper for the creation of Photosynthetically Active Radiation Sensor using an Array of Light Sensors with the Integration of Data Logging for Agricultural Application.","PeriodicalId":405664,"journal":{"name":"2018 3rd International Conference on Computer and Communication Systems (ICCCS)","volume":"13 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115523346","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
