The evolving nature of competition in the wireless ecosystem : emergent opportunities and threats

Thesis (S.M.)--Massachusetts Institute of Technology, System Design and Management Program, 2009.This electronic version was submitted by the student author. The certified thesis is available in the Institute Archives and Special Collections.Cataloged from student submitted PDF version of thesis.Includes bibliographical references.By the end of 2008, there are over 4 billion mobile cellular subscriptions worldwide, translating into a penetration rate of 61%. In developed economies like the United States, the penetration rate has reached over 85%. Even though the subscriber numbers are reaching saturation levels, the revenues of mobile operators continue to grow at a double-digit rate. This is primarily because of an increase in data usage over cellular networks. Mobile handsets have become increasingly powerful and rival the capabilities of personal computers from just a few years ago. These devices can be used to run a variety of applications and are fast becoming the medium of choice for accessing the Internet. Cellular networks are also becoming increasingly powerful in their ability to carry large amounts of data. This evolution in capabilities has attracted a variety of new players to the wireless ecosystem changing the nature of interaction within the ecosystem. The central role played by the wireless operators is increasingly challenged by these new entrants creating both new opportunities and new threats for all the participants in the ecosystem. This thesis will explore the structure of the wireless ecosystem as it exists today and analyze how competition between various layers and within each layer has played out. Further, it will look at the new ways in which the participants are competing with each other and how this results in emergent opportunities and threats. Finally, the thesis will draw lessons from the Internet revolution and the personal computing ecosystem to predict how the platform wars are likely to play out and who has the opportunity to become the dominant player in the new ecosystem.by Nagarjuna Venna.S.M

Visual Servoing Using an Autonomous Quadcopter

The goal of this project is to make autonomous quadcopter track and follow a given object in 3D space. We use visual servoing and adapted such that it can autonomously guide a quadcopter. In this poster we explain the technique and results

Real-time Robot Control Using Leap Motion Technology

Unlike pre-programmed controlling, real-time control of a 6-DOF manipulator is a complex task which involves physical interaction with a traditional manual controller clustered with numerous joysticks. This take lot of joystick movements in order to bring the robotic arm to a position followed by an action with the end-effector. Using the latest technology in human computer interaction, i.e. Leap Motion, we can reduce the complexity of this task to minimum effort by making the robotic arm mimic human hand in real time

Design and Development of near space Robotic Monkey

High altitude robotics provides an opportunity to explore the “Near space” environment. Our project proposes to create a prototype of a high altitude robotic monkey puppet, which can operate in near space conditions. This project is envisioned around the first animal that USA sent to into space monkey named ALBERT1(Fig 1). This high altitude robotic puppet HAM (High Altitude Monkey), is scheduled to be launched as a payload on a helium balloon. Commanded from a ground station at the University of Bridgeport, HAM can execute a set of predetermined actions, with a live video feedback both from within and outside the payload capsule. This paper outlines and discusses the several technical and logistical design challenges and solutions encountered in the design and development of HAM

Real-Time Robot Control Using Leap Motion A Concept of Human-Robot Interaction

© ASEE 2015With the advent of robots in various industries, countless tasks that are complex for humans are made easier than ever before. Thanks to their functionality and accuracy we are able to achieve high productivity while investing less cost. As we see into our future of manufacturing industries, we also see that robots will replace most of the human workers to achieve faster production. All these areas use automated robotic arms which do certain tasks assigned to them with amazing speeds and pin point accuracy, because of the mathematical calculations done by the computer and are not manually controlled by humans. However, no robot can match the dexterity of a human hand. In order to control a robotic arm manually, the operator should carefully manipulate every joint in the arm to a perfect angle. Just as it sounds, it is very tedious to control them manually, that’s why they are left to the computers. But, areas such as medicine, space research, and military robotics require robot arms to be manually controlled to operate with objects that cannot be dealt with human hands. Existing systems provide traditional controllers that are not efficient to handle a robotic arm and is time consuming. To achieve speed and accuracy like automated robots, we need a new approach that can bridge this gap. Here comes the Leap Motion Technology, a latest invention in Human-Computer interaction area. Using this device we track a human hand in air accurate to millimeter. The position of hand is then used to calculate the joint angles that in turn help us to rotate the robotic arm joints by the computer with blazing speeds

Pengaruh Self Efficacy terhadap Employee Engagement dan Kinerja Karyawan (Studi pada Karyawan PT Telekomunikasi Indonesia Regional V Surabaya)

This study examines the effect of self efficacy on employee engagement and employee performance on the employees of PT Telekomunikasi Indonesia Regional V Surabaya. This research is motivated by the importance of self efficacy in order to increase employee engagement and employee performance. Employee performance can be influenced by many factors including self efficacy and employee engagement. High employee performance will determine the success of the company, the company will be able to survive in a competitive environment if supported by employees who have enthusiasm and good ability to work. The results showed that there was a significant influence of a) self efficacy on employee engagement of 0.619 (61.9%), b) there was significant influence of self efficacy on employee performance of 0.431 (43.1%), c) significant from employee engagement to employee performance of 0,414 (41,4%) d) indirect effect for self efficacy on employee performance through employee engagement equal to 0,256 (25,6%). Based on the results of the above research, it is suggested that PT Telekomunikasi Indonesia Regional V Surabaya to pay attention and provide guidance and guidance to employees to increase confidence, need to supervise the employees regarding tasks, position and improve technology to be easy to operate.

HUBUNGAN KEAHLIAN KOMITE AUDIT TERHADAP KUALITAS LABA PADA PERUSAHAAN SEKTOR MANUFAKTUR YANG TERDAFTAR DI BEI TAHUN 2012-2014

Abstrak - Penelitian ini bertujuan untuk mengetahui hubungan keahlian komite audit dengan kualitas laba perusahaan dengan menggunakan manajemen laba sebagai proxy. Keahlian komite audit dibedakan menjadi dua, yaitu keahlian berdasarkan dan pengalaman kerja. Digunakan sampel dari data sekunder perusahaan manufaktur yang terdaftar di BEI pada 2012-2014 dan manajemen laba perusahaan dihitung menggunakan model modified Jones. Hasil penelitian menunjukkan bahwa komite audit yang memiliki pendidikan akuntansi dalam komposisi komite audit akan menurunkan tingkat manajemen laba dan meningkatkan kualitas laba, sedangkan semakin banyak anggota komite audit yang tidak memiliki pengetahuan mengenai akuntansi akan mendorong terjadinya manajemen laba dan menurunkan kualitas laba perusahaan. Kata kunci: Manajemen Laba, Komite Audit, Keahlian Abstract – The purpose of this study is to determine the relationship of the audit committee expertise with the earnings quality by using earnings management as a proxy. Audit committee expertise is divided into two categories, there are the expertise that comes from education and work experience. Used a sample of secondary data companies listed on the Indonesia Stock Exchange in 2012-2014 and earnings management is calculated using a modified model of Jones. The results showed that the audit committee has the accounting education in the composition of the audit committee will reduce the level of earnings management and improve the earnings quality, while a growing number of audit committee members who do not have knowledge of accounting leads to a lowering of earnings management and earnings quality.
