Internet of Things (IoTs) is gaining increasing significance due to real-time communication and decision making capabilities of sensors integrated into everyday objects. Predicting performance in IoTs is critical for detecting performance bottlenecks, designing optimal sleep/wake-up schedules and application-aware performance tuning. However, performance prediction becomes a significant challenge...
This article presents a data audit system, which confirms that proper use of data is performed on the iKaaS platform (intelligent Knowledge as a Service) platform. The proposed data audit system can alleviate ambiguous anxiety of data owner about unauthorized use by providing measures to understand that illegal use of data cannot occur. This achievement is expected to support the construction of the...
With continuous scaling of CMOS technology, a key issue for the microprocessor and application processor industries is the reliability of silicon. Two salient problems with silicon are Bias Temperature Instability (BTI), which increases the threshold voltage of MOSFETs, and Gate Oxide Breakdown (GOBD), which decreases the gate leakage resistance. Both pose severe limitations for sub-micrometer transistors...
Crowdsensing applications rely on volunteers to collect sensor readings using their mobile devices. Since the collected sensor readings are annotated with spatiotemporal information, the volunteers' privacy may be endangered. Existing privacy-preserving solutions often disclose the volunteers' location information to either a central third party or their peers. As a result, the volunteers need to...
In this paper, we are presenting a data flow and fault management architecture, developed for an event driven wireless sensor network used in landslide surveillance. Our concept system collects landslide data using a dedicated wireless sensor network. The WSN was configured with tree architecture and contains one gateway, relay nodes, and multiple end nodes. The WSN components were distributed in...
The IMB-CNM (Barcelona) has developed a new vertical JFET (V-JFET) technology with the purpose of working as rad-hard switches in the HV powering scheme of the upgraded ATLAS tracker. The design of the new transistors draws upon a deep-trenched 3D technology to achieve vertical conduction and low switch-off voltage. These features prospect suitable radiation hardness for the application. The first...

The Poznan Supercomputing and Networking Center (PSNC) together with NoviFlow Inc. and Spirent have jointly developed a demonstration showing how programmable SDN infrastructure can be utilized to significantly simplify the onboarding and provisioning...
The detection of molecular markers such as micro ribonucleic acid (miRNA) expression levels in the cells are essential for diagnosis of a disease, especially cancer. Recently, a huge amount of molecular markers on cell is being extracted by single molecular detection method, as results, excessively detection process and time is required. Meanwhile DNA computing has capabilities to interact with biological...
Metal oxide based thin film transistors (TFT) have shown strong improvement of their electric characteristics with n-type devices being gradually introduced commercially in display technology.

In this work, graphene/InN nanowire (NW) heterostructure based diode and field effect transistor devices are studied for potential gas sensing applications. InN NWs were grown on SiO2/Si substrate and CVD grown graphene was then transferred on them to make a graphene/InN diode structure. Some of the NW samples were treated with O2 plasma for various durations of time before transferring graphene,...
In this paper, a differential p-channel ion-sensitive field-effect transistor (ISFET) based pH sensor is presented. The sensor has been implemented in a 180nm 1-poly 6-metal standard CMOS process. The sensor uses a larger sensing gate area for improved sensitivity. Simulation results show that the designed single-chip ISFET based pH sensor provides an ISFET sensitivity of 50 mV/pH over a 1–14 pH range...
The paper describes the sixth edition of Rapid Environmental Picture Atlantic exercise (REPIS-Atlantic) which took place in July 2015 off the Portuguese islands of Azores to demonstrate coordinated operations of unmanned underwater, surface, and air vehicles contributed by participants coming from Europe and the United States of America. REP-Atlantic is a yearly demonstration exercise targeted at...
We describe a system for ocean observatories which streams data from the seafloor to shore in near real-time without a cable or moored surface buoy. The system utilizes a Wave Glider® (Liquid Robotics, Inc.); an autonomous surfboard-sized maritime vehicle that harvests wave energy for propulsion and solar energy for electrical power. The Wave Glider acts as a communications gateway as it hovers on...
Cyber-physical Systems (CPS) have components deployed both in the physical world, and in computing environments, such as smart buildings or factories. Elastic Cyber-physical Systems (eCPS) are adaptable CPS capable of aligning their resources, cost, and quality to varying demand. However, failures can appear at run-time in the physical or software resources used by the eCPS. Failures can have different...
Emergency situations, such as fire incidents or terrorist attacks, have imposed strongest safety requirements for crowds gathering. The enhancement of situation awareness, decision support and emergency notification systems that facilitate the safety and effectiveness of evacuation processes in a major incident is therefore of utmost importance. ICT, IoT and smart systems have gained much attention...
The extreme resolution of CO2 gas molecules sensing, i.e., detection of single molecule, is reported. The suspended bilayer graphene beam is exploited in order to isolate the sensing part of the device from the substrate noise. Using the electrostatic force, the central part of the suspended beam is pulled-down to bottom metal electrode, which leads to two slanted graphene beams in suspension with...

Recently, several CMOS PLDs were reported using nonvolatile memory technologies for array implementation. However, the architecture of these CMOS PLDs are limited in only one programmable array feeding into a group of fixed OR gates. Therefore, the efficiency of its logic integration is greatly limited due to lack of product term sharing capability. This paper will describe a 25ns, 50mA CMOS Programmable...
