However this density has made the products often, to fail in the market window. It is widely accepted amongst the engineering community that a large proportion of development effort and delays is due to very extended, detailed, prone to bugs and repetitive low level simulations generated by attempts to cover most corner cases. This paper discusses a Formal High-level Synthesis - based verification method, that is based on high-level compile and execute of program code, and produce simulation engines from various levels in the design flow. Eventually the produced “simulators” execute and converge to the same results, since the Synthesis process is formal. The complete, and rapidimplementation flow is formal becaue the automated cycle-accurate simulator is generated from the the same formal optimized model used by the completed High-level Synthesis flow. A huge number of benchmarks from real-life applications, a few of which are discussed here, were developed and validated with the method presented in this paper and always the formal nature of the tools helped to catch all of the bugs as early as possible in the implementation flow.","PeriodicalId":68279,"journal":{"name":"计算机工程与设计","volume":"197 1","pages":"1-5"},"PeriodicalIF":0.0,"publicationDate":"2021-09-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"75009878","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}

The wide use of masks, that are essential for the reduction of the spread of the virus, has been declared mandatory by several institutions and countries. Given the circumstances, masked facial recognition has gained an increased attention by the research community. Mask identification for healthcare reasons, face recognition and identification for public safety in a smart city environment and security reasons proved to be a challenging problem with most algorithms having limitations. The vast amount of data, of people with masks, that has been generated in the recent months will be helpful in tackling some of the major issues. The main issues most methodologies face are occlusion, illumination, non-frontal characteristics and pose variation. This paper focuses on the preliminary results of a novel rule based hybrid masked face recognition algorithm. We use the MaskedFace-net dataset and we detect the covered face using the Viola-Jones algorithm. Through the use of Statistical Region Merging (SRM) we detect the ocular region in the cropped face image, and we achieve eye detection for our preprocessing. Through this process we manage to get a clearer and sharper version of the original input eye image. Finally, we generate the attributed graph of the detected facial features, whose labeled arcs represent the computed distance rations between them. This algorithm will act as input into a machine learning prediction model moving forward.","PeriodicalId":68279,"journal":{"name":"计算机工程与设计","volume":"15 1","pages":"1-6"},"PeriodicalIF":0.0,"publicationDate":"2021-09-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"75015997","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}

The rapid increase of traffic load combined with the emergence of new network requirements has led to the need of developing a network architecture capable of supporting a network of high efficiency, improved transmission rates and low latency. C-RAN architecture is able to meet all these challenges, while focuses on the innovation of a functional split in the Base Station (BS) where the Baseband Units - BBU is detached from the Remote Radio Heads - RRH. Its successful implementation is able to bring significant benefits where among them cost reduction, the entrance of new network requirements and services as well as enhanced network flexibility, are the ones that dominate. In this paper, we perform the analysis of this type of network through the application of specific Teletraffic Models: the Multi-rate Loss Model and the Retry Models. The Multi-rate Loss Model refers to systems that serve different types of services, whose calls are accepted by the system if only there are service units available. The Retry Models allows rejected calls to retry their connection to the system, offering a lower chance of losing calls and thus reduced network performance. The comparison of the blocking probabilities can lead us to conclusions about the efficiency of these models in a C-RAN network and then in the evaluation of the overall network performance.","PeriodicalId":68279,"journal":{"name":"计算机工程与设计","volume":"45 1","pages":"1-5"},"PeriodicalIF":0.0,"publicationDate":"2021-09-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"81002692","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}

We constructed genetic risk models, with the aim to assess their predictive performance on melanoma risk. Summary level data from the largest meta-analysis of genome-wide association studies for melanoma, up to date, were used for the construction of weighted genetic risk scores. We used six different p-value thresholds for genetic variants inclusion. We evaluated our genetic risk scores in 2,862 events of incident melanoma and 321,789 cancer-free controls from the UK Biobank, a prospective cohort study of 500,000 participants. Using AUCs, we compared the predictive ability of the different genetic risk scores. Genetic risk scores were strongly associated melanoma risk. Odds Ratios ranged from 1.478 to 1.528. The predictive ability of the genetic risk scores ranged from 0.6234 to 0.6328 showing a moderate performance. Our study suggests that when the p-value threshold for genetic variants inclusion become more tolerant, the prediction performance of the model improved. Validation of the results in larger populations, as well as Southern European populations is needed.","PeriodicalId":68279,"journal":{"name":"计算机工程与设计","volume":"79 2 1","pages":"1-4"},"PeriodicalIF":0.0,"publicationDate":"2021-09-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"90962619","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}

Although, these apps are used daily for shortest paths calculation within the urban centers, they were designed with an emphasis on the needs of motor vehicles and therefore pedestrian routes have only been considered as an add-on option. For that reason, current pedestrian navigation services provide routes based on road networks as they are well defined due to the popularity of car navigation systems on one hand and the lack of pedestrian data (including streets, sidewalks, curb ramps, elevation data, and construction permit information) on the other hand. However, road networks do not adequately represent the paths that pedestrians use. Furthermore, for people with limited mobility, planning a route using a wheelchair in urban centers is very difficult due to lack of information regarding accessibility along the route. To this end, better data on pedestrian sections are needed to improve safety, comfort, and convenience of pedestrian movement. This process requires a carefully developed methodology for modeling pedestrian routes. This paper introduces a structured approach to develop a simple model of pedestrian data that captures all required information and facilitates the design of user-friendly interactive navigation systems. A pilot case is presented for the historical center of Thessaloniki city.","PeriodicalId":68279,"journal":{"name":"计算机工程与设计","volume":"39 1","pages":"1-4"},"PeriodicalIF":0.0,"publicationDate":"2021-09-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"75358228","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}
