Risk is often discussed in connection with public-private partnerships (P3s), and risk allocation likely a determinant of P3 success or failure. Despite being central to the delineation risks, contracts have not been used directly examine risks P3s, particularly United States. Employing systematic content analysis framework, 31 21 U.S. highway was determined. These represent entire population projects from 2004 through first quarter 2016 exception one project whose contract made available....

Accurate step counting is essential for indoor positioning, health monitoring systems, and other positioning services. There are several publications commercial applications in counting. Nevertheless, over-counting, under-counting, false walking problems still encountered these methods. In this paper, we propose to develop a highly accurate method solve limitations by proposing four features: Minimal peak distance, minimal prominence, dynamic thresholding, vibration elimination, features...

Public–private partnerships (PPPs) are multilateral transactions implemented over long-time horizons; hence, they complex arrangements that face various forms of uncertainty. These characteristics have made them a subject research in variety fields. The nature the transaction has attracted scholars who examined context agency theory, incomplete contracts and cost economics (TCE). prevalence life-cycle uncertainty PPPs is at root many contractual issues, such as incentive allocation, high...

Abstract Background The present study aimed to deliver a replicable transcriptomic map of migraine without aura (MO) and its comprehensive, genome- drug discovery focused analysis identify hypotheses for future research- clinical attempts. Methods We recruited 30 controls 22 MO patients serious chronic comorbidities/regular medication intake. RNA-sequencing was conducted interictally at two different time points differential gene expression enriched pathways. Subsequent refining functional...

Multitemporal synthetic aperture radar (SAR) interferometry (InSAR) is a widely used technique to measure the ground subsidence and has already shown its ability map such phenomena on large spatial scale with millimetric accuracy from space. In Vietnam, have independent SAR data for surface risk applications, new X-band mission (JV-LOTUSat) been scheduled launch 2019-2020 timeframe. However, Vietnam located in tropical regions where their conditions are impacted by strong atmosphere. The aim...

While working on fire ground, firefighters risk their well-being in a state where any incident might cause not only injuries, but also fatality. They may be incapacitated by unpredicted falls due to floor cracks, holes, structure failure, gas explosion, exposure toxic gases, or being stuck narrow path, etc. Having acknowledged this need, study, we focus developing an efficient portable system detect firefighter's falls, loss of physical performance, and alert high CO level using...

[Context] Software developers often spend a significant portion of their resources resolving submitted evolution issue reports. Classification or prediction lead time is useful for prioritizing issues and supporting human allocation in software maintenance. However, the predictability still research gap that calls more empirical investigation. [Aim] In this paper, we empirically assess different types models using factor measures collected from tracking systems. [Method] We conduct an...

Abstract Difficulty falling asleep is one of the typical insomnia symptoms. However, intervention therapies available nowadays, ranging from pharmaceutical to hi-tech tailored solutions, remain ineffective due their lack precise real-time sleep tracking, in-time feedback on therapies, and an ability keep people during night. This paper aims enhance efficacy such by proposing a novel aid system that can sense multiple physiological signals continuously simultaneously control auditory...

This paper presents a two-step algorithm for online trajectory planning in indoor environments with unknown obstacles. In the first step, sampling-based path techniques such as optimal Rapidly exploring Random Tree (RRT*) and Line-of-Sight (LOS) are employed to generate collision-free consisting of multiple waypoints. Then, second constrained quadratic programming is utilized compute smooth that passes through all computed The main contribution this work development flexible framework can...

Risk is often discussed in connection with public-private partnerships (PPPs). Despite being central to the delineation and allocation of risks, contracts have not been used directly examine risks PPPs, especially US. This pilot investigation examines risk related provisions four Virginia highway PPP projects whose total value $5.4 billion. A developed matrix rubric supported content analysis contracts, which identified 27 their allocation, sharing mechanisms. The study consequently...

The rapidly developing urbanization since the last decade of 20th century leads to strong groundwater extraction, resulting in subsidence phenomena Hanoi, Vietnam. Recent advances multi-temporal spaceborne SAR interferometry, especially with Persistent Scatters Interferometry (PSI) approach, is robust remote sensing technique for measuring ground large scale millimetric accuracy. This work has presented an advanced PSI analysis, provide unprecedented spatial extent and continuous temporal...

Various intervention therapies ranging from pharmaceutical to hi-tech tailored solutions have been available treat difficulty in falling asleep commonly caused by insomnia modern life. However, current techniques largely remain ill-suited, ineffective, and unreliable due their lack of precise real-time sleep tracking, in-time feedback on the therapies, an ability keep people during night, a large-scale effectiveness evaluation. Here, we introduce novel aid system, called Earable, that can...

Abstract This paper introduces two physical modeling standards in the gas turbine and cycle analysis context. Modelica is defacto standard for system simulation. The Functional Mock-Up Interface a domain-independent model exchange (“engine decks”). summarizes key language concepts discusses important design patterns application of simulation to acausal language. To substantiate how open are applicable simulation, closes with examples, conventional unmixed turbofan thermodynamic weight as...

Using mobile phones during traffic progress is one of the main causes accidents because drivers do not focus on driving, they try to listen phone calls or text some messages... Most research work has focused car driving.However, using motorbike very popular in developing countries such as Vietnam, India, etc. Up now, there are just a few works, which driving with obvious limitations.Thus, this research, we proposed complete solution for bikers who own smartphone.Our exploits information from...
