The automotive industry is growing rapidly. Many innovations are being focused on the automotive industry and the connected vehicles concept is becoming more reality than ever. The vehicle is being connected to the cloud for more features and better control. A previous paper, “Firmware Over the Air for Automotive, FOTAMOTIVE” was published [1]. One of the main challenges for FOTAMOTIVE is the cost of the bandwidth for over the air updates. This paper introduces a new solution to download the update files without the need of a connection to the internet. This new solution consists of downloading the update files from other vehicles within reasonable range that already have the update files via the Ad-Hoc Network architecture proposed in this paper. We are presenting Fotanet architecture, process flow chart, system components, vehicle cloud management, simulation and results. Based on the statistical data collected, an average visit to the dealer cost $150. The cost for an ECU update via Fotanet is free, but there are still some development and maintenance costs to the OEM. These costs are spread out to how many vehicles/ECU are being updated. The more updates there are, the less the cost will be. For example, if it cost one million dollars to develop and maintain Fotamotive and Fotanet, the cost per update would be $10 for 100k updates and $1 for 1 million updates. Based on the statistical data collected on the average number of vehicles sold by various OEMs, the cost is expected to be minimal.
汽车工业正在迅速发展。许多创新都集中在汽车行业，互联汽车的概念比以往任何时候都更加现实。该车正在与云连接，以获得更多功能和更好的控制。之前的一篇论文，“固件Over the Air for Automotive, fotamautomotive”发表[1]。fotammotive面临的主要挑战之一是无线更新的带宽成本。本文介绍了一种无需连接到internet即可下载更新文件的新方案。该解决方案通过本文提出的Ad-Hoc网络架构，从合理范围内已有更新文件的其他车辆上下载更新文件。我们将介绍Fotanet架构、流程流程图、系统组件、车辆云管理、仿真和结果。根据收集到的统计数据，平均一次拜访经销商要花费150美元。通过Fotanet更新ECU的费用是免费的，但OEM仍然需要支付一些开发和维护费用。这些费用分摊到正在更新的车辆/ECU的数量上。更新越多，成本就越低。例如，如果开发和维护fotammotive和Fotanet需要花费100万美元，那么每次更新的成本为10万次更新10美元，100万次更新1美元。根据各原始设备制造商的平均销量统计数据，预计成本将是最低的。

This paper presents a lossless double-precision floating point compression algorithm. Floating point compression can reduce the cost of storing and transmitting large amounts of data associated with big data problems. A previous algorithm called FPC performs well and uses predictors. However, predictors have limitations. Our program (fzip) overcomes some of these limitations, fzip has 2 phases, first BWT compression, second value and prefix compression with variable length arithmetic encoding. This approach has the advantage that the phases work together and each phase compresses a different type of pattern. On average, fzip achieves a 20% higher compression ratio than other algorithms.

Multiple Hypothesis Tracking (MHT) is an active field for the detection and tracking of low-observable small targets. Most of MHT algorithms are based on a search method in a large tree of possible tracks in a digital image sequence. Though, processing a tree structure with a significant number of branches in MHT has been a challenging issue. Tracking high-speed objects with traditional MHT requires some presumptions which limit the capabilities of these methods. This paper presents a novel MHT system in three steps to solve this problem. The process starts with the root of each track in the video sequence followed by a Particle Swarm Optimization (PSO) search to find the optimum tracks. Iterative process of PSO tries to refine each track. In the third step, the proposed algorithm merges all of the refined tracks related to an object. Efficiency of the proposed method is presented through the figures and tables in the simulation results section.

The lightweight and low-cost 3-dimensional depth sensors have gained much attention in the computer vision and robotics community. While its performance has been proven successful in the robotics community, these sensors have not been utilized successfully for many assistive devices. Leveraging on this gap, this paper presents the design, implementation, and preliminary evaluation of a haptic feedback system for the blind using 3-D depth sensors. The proposed portable system interprets the visual scene using the depth sensor, converts it into distance map, processes, and evaluates this information using a tablet computer. In addition, it provides haptic cues to the user through an array of vibration motors woven into the gloves. Throughout preliminary evaluation, this system has shown to successfully identify, track, and present closest objects, closest humans, multiple humans, and perform real-time distance measurements.

In this paper, we address the issue of interference between Wireless Body Area Networks(WBANs) with different medical emergency levels. The inter-WBAN interference could potentially degrade the Quality of Service (QoS) performance of sensor nodes. Furthermore, such interference leads to a fatal situation when WBANs belong to patients with different emergency condition. A game-theoretic scheme is proposed to tackle the inter-WBAN interference issue and improve the reliability of data for WBANs with different emergency levels. We formulate the interference between WBANs as “infinite repeated game” and model the emergency levels using the heterogeneous discount factors. We propose a “grim” strategy for the repeated game and investigate the conditions in which this strategy holds “Subgame Perfect Equilibrium” property. Finally, we evaluate the performance of our approach using simulation model.

Most individuals do not realize they have a broken vein in the eye until somebody lets them know or they look in a mirror. This condition is not tormenting, but commonly creates obtuse trauma to the eye. Treatment is often not required for subconjunctival drainage. In the event that a patient has recognized the presence of blood in his or her eye, it may be fitting for him or her to look for medical consideration. While a subconjunctival drain is occasionally risky, hyphema (blood in the front assembly of the eye, between the cornea and the iris) is conceivably a more serious condition, with more serious outcomes. This paper first provides an overview of the most common techniques used to calculate the blood vessels in color images of the retina. Then, it presents a study that has been conducted to discuss the early steps of the intraocular pressure (IOP) detection in the eye, using histogram analysis.

Identifying the exact current location of a robot is a fundamental prerequisite for successful robot navigation. To precisely localize a robot, one popular way is to use particle filters that estimate the posterior probabilistic density of a robot's state space. But this Bayesian recursion approach is computationally expensive. Most microcontrollers in a small mobile robot cannot afford it. We propose to use a smartphone as a robot's brain in which heavy-duty computations take place whereas an embedded microcontroller on the robot processes rudimentary sensors such as ultrasonic and touch sensors. In our design, a smarphone is wirelessly connected to a robot via Bluetooth by which distance measurements from the robot are sent to the smartphone. Then the smartphone takes responsible for computationally expensive operations like executing the particle filter algorithm. Also we propose to use rotating ultrasonic sensors to reduce the number of sensors needed as well as time of distant measurements. In this paper, we designed a mobile robot and its control architecture to demonstrate that the robot can navigate indoor environment while avoiding obstacles and localize its current position. Several experiments were conducted to show feasibility of the rotating sensors and a smartphone brain for a mobile robot.

Recently, several measures are being taken to conserve energy without degradation in performance. To achieve notable energy savings in elevator systems, in this paper we develop and experimentally test an algorithm. Operation of an elevator can be classified into two modes: running mode and stand-by mode. We design an elevator system capable of energy-saving by manipulating its speed in running mode. Speed is varied based on the difference of load carried and the counter weight. A miniature elevator model is used to carry out the experiments and to collect energy data. The algorithm is tested on different traffic patterns: 1) pre-determined pattern, and 2) random pattern. Voltage and current samples are collected from the miniature elevator model, The final energy data of variable speed system are calculated and compared with energy data of constant speed system. This proposed method results in a 3.715% energy savings for pre-determined traffic pattern and 8.7612% energy savings for random traffic patterns.

A graphical/numerical technique is presented for the extraction of roots (poles and zeros) of RC and RL circuits, where the roots lay on the real axis in the s-plane. The method constructs a corresponding LC circuit for the RC or RL circuit, and as demonstrated, all real axis roots are shifted to the jω axis, where the swiping-frequency signals exit. The process takes place in two steps: in the first step the roots in the real axis RHP (RRHP), if any, are mirrored to the real axis LHP (RLHP), and in the second step the roots on the RLHP are moved to the jω axis. It is also shown that the magnitude of the corresponding roots in the two circuits, RC (or RL) and the corresponding LC, relate by a scaling factor log(ωC) = log(ωR)/2.
