Artificial intelligence (AI) has been altering industries as evidenced by Airbnb, Uber and other companies that have embraced its use to implement innovative new business models. Yet we may not fully understand how this emerging rapidly advancing technology influences model innovation. While many are being made vulnerable competitors equipped with AI technology, study attempts focus on the proactive side of drive Describing catalyst innovation, sheds light contingent factors shaping...
This paper presents a wide dynamic range (DR) CMOS root-mean-square power detector with temperature variation compensation technique in 28-nm process. The cascaded gain amplifiers and squaring circuits the proposed can achieve DR level segmented detection method using switch driver help of modem. A 12-bit current digital-to-analog converter is used to calibrate dc offset 25- <formula formulatype="inline" xmlns:mml="http://www.w3.org/1998/Math/MathML"...
Multimode cellular RFICs need high dynamic range in order to simultaneously satisfy the linearity requirements of LTE and low-noise performance 2G. Traditionally, SAW filters are employed relax noise-linearity trade-off at cost higher BOM. In a highly competitive market, mobile devices support >35 bands, number which is expected rise further future, providing strong motivation for SAW-less transmitter (TX) design. An TX operating single resource-block (RB) mode susceptible spurious...
As LTE offers the best wireless experience as never before, people spend much more time on smartphones to enjoy internet surfing and social networking, etc. To further improve network efficiency, recently, Power-Class 2 (PC2) High Power User Equipment (HPUE) applied B41 is deployed. support HPUE, RF transmitters (TXs) need deliver higher output power while maintaining stringent linearity requirements of emission mask, especially for third-order Counter Intermodulation (CIM3) in one Resource...
Purpose Workforce diversity is becoming a crucial matter in the area of internal communication. Realizing that there are multiple brackets within body workforce (i.e. audience), purpose this paper to develop an intermediate approach manage by segmenting audience. Design/methodology/approach Developing segmentation for managing diversity, authors recommended use few mathematical methodologies, including expectation-maximization algorithm, partial least squares structural equation model...
In this article, unconstrained trust region methods are studied and applied in aerodynamic shape optimization. Trust high-performance gradient-based optimization methods. The theory of is explained, a subproblem solved using the dogleg method Moré–Sorensen method. After verifying via analytical test problems, they to design for transonic subsonic flows.
In this study, a reliability analysis was performed for the aerodynamic analysis. Among various methods, moment method used and results were compared with other methods. The of 2D airfoil, 3D wing body configuration considered. case computed by parameterising an airfoil shape using PARSEC function considering uncertainties its shape. configuration, it flow conditions.
The World Health Organization and the American College of Sports Medicine have released guidelines on physical activity sedentary behavior, as part an effort to reduce inactivity worldwide. However, date, there is no computational model that can facilitate integration these recommendations into health solutions (e.g., digital coaches). In this paper, we present operational machine-readable represents able reason about guidelines. To end, adopted a symbolic AI approach combines two paradigms...
This study presents an ecien t strategy for reliability analysis under multidisciplinary systems. Existing methods have performed the using nonlinear optimization techniques. is mainly due to fact that they directly apply Multidisciplinary Design Optimization(MDO) frameworks formulation. Accordingly, and Analysis(MDA) are tightly coupled in a single optimizer, which hampers utilizing recursive functionapproximation based such as Advanced First Order Reliability Method(AFORM). In order...
Based on robustness of split-gate embedded Flash (eFlash) bit-cell, 28-nm eFlash process with IP (20Mb) and SRAM (32Mb) is developed for automotive Grade 1 (G1) application temperature range (-40~150°C) the first time. In case single flash cell evaluation, sufficient sensing margin tight current distribution, decent endurance retention characteristics have been demonstrated. A new type scheme introduced to compensate degradation at high temperature, called SAPVL (Sense amp Proportional...
본 논문에서는 CFD/FreeWake 연계해석방법을 이용하여 헬리콥터 로터의 공력을 해석하였다. 연계해석방법은 CFD를 로터주변의 얻고, 후류의 거동은 FreeWake를 모사한다. FreeWake 모델은 CFD의 경계조건을 제공하고, CFD는 후류형성을 위한 로터블레이드 양력변화율을 제공하는 방법으로 연계된다. 다른 로터공력해석 방법에 비하여 높은 정확도와 계산 시간 절감으로 효율적인 계산을 가능하도록 한다. this study, helicopter rotor flow is simulated by using a tightly coupled method to describe wake characteristics and calculate the field aerodynamics. In method, freewake model provides boundary condition required in CFD calculation pressure distribution on blade...
We propose a semantic dietary coaching system for personalized chronic disease management. Technically, we built three types of knowledge graphs (KGs): guideline graph, food and user health graph. These respectively represented prestigious guidelines, ingredients nutrition information from over 500 thousand recipes, as well an individual's lifelog mobile wearable devices status. Through reasoning the KGs, provided through intake diagnosis menu selection. Expert verification showed that our...
The role of uncertainty in data management has become more prominent than ever before, especially because the growing importance machine learning-driven applications that produce large uncertain databases. A well-known approach to querying such databases is blend rule-based reasoning with uncertainty. However, techniques proposed so far struggle In this paper, we address problem by presenting a new technique for probabilistic exploits Trigger Graphs (TGs) -- notion recently introduced...
Early depression detection research employs machine learning models trained on crowd-sourcing data.
