The Signalling System No. 7 (SS7) is used in GSM/UMTS telecommunication technologies for signalling and management of communication. It was designed on the concept private boundary walled technology having mutual trust between few national/multinational operators with no inherent security controls 1970s. Deregulation, expansion, merger data networks have vanquished walls hence increasing number service providers, entry points, interfaces to SS7 network, which made it vulnerable serious...

Automated dental imaging interpretation is one of the most prolific areas research using artificial intelligence. X-ray systems have enabled clinicians to identify diseases. However, manual process disease assessment tedious and error-prone when diagnosed by inexperienced dentists. Thus, researchers employed different advanced computer vision techniques, as well machine deep learning models for diagnoses imagery. In this regard, a lightweight Mask-RCNN model proposed periapical detection....

Given the high prevalence and detrimental effects of unintentional falls in elderly, fall detection has become a pertinent public concern. A Fall Detection System (FDS) gathers information from sensors to distinguish routine activities order provide immediate medical assistance. Hence, integrity collected data becomes imperative. Presence missing values data, caused by unreliable delivery, lossy sensors, local interference synchronization disturbances so forth, greatly hamper credibility...

Software engineers post their opinions about various topics on social media that can be collectively mined using Sentiment Analysis. Analyzing this opinion is useful because it provide insight into developers’ feedback tools and topics. General-purpose sentiment analysis do not work well in the software domain most of these are trained movies review datasets. Therefore, efforts underway to develop domain-specific for Engineering (SE) domain. However, existing SE struggle compute negative...
