EZchip Semiconductor. EZchip Semiconductor Ltd. was a publicly traded fabless semiconductor company, headquartered in Yokneam, Israel, that developed and marketed Ethernet network processors. It was acquired by Mellanox Technologies in 2016.

History 
EZchip was co-founded in 1999 by Eli Fruchter, a Technion graduate in the field of electrical engineering and veteran of the Israel Defense Forces' 8200 intelligence unit, and Alex Tal who served as Ezchip's first  CTO and V.P R&D. Until 2008, EZchip operated as a subsidiary of LANOptics, then a developer of Ethernet switching chips and security software. After LANOptics completed its full acquisition of EZchip in January 2008, it changed its name to EZchip and its ticker symbol from LNOP to EZCH. Over the twelve-month period leading up to February 2012, shares of EZchip rose 40% on the Nasdaq index as demand for its processors grew and speculation increased that the company would get bought out.

In July 2014, EZchip  acquired Tilera, a company that develops high-performance multi-core processors, intelligent network interface cards and white-box appliances for data-center networking equipment, $130 million in cash.

In January 2016, a shareholder vote passed that approved the merger of Mellanox Technologies and EZchip. The acquisition was completed on 23 February 2016.

Urban Ecological Park. The Urban Ecological Park (Spanish: Parque Ecológico Urbano), also known as the Ponce Ecological Park (Spanish: Parque Ecológico de Ponce), is a passive park in Ponce, Puerto Rico. The park was designed by Bonin Orozco Arquitectos and was inaugurated on 19 September 2012. The park is unique in that it was designed to create a "green lung" in the city by using ecological mindset in its entirety, from the construction materials used to the design and other areas as well. Except for one tree that got relocated within the project, the new park made use of all the existing trees and shrubs as they existed on the site prior to the development of the park.

History
Design of the park was by Bonnin Orozco Arquitectos. The municipality started construction on 10 March 2010. By February 2012, 46% of the construction had been completed. It was scheduled to open in August 2012, and the inauguration date was set for 24 August 2012, but due to Hurricane Isaac that week, it was postponed several weeks. The park was finally inaugurated on 19 September 2012. It was inaugurated with the animation of various artists including Dagmar, Glenn Monroig, Jackeline Capó and Ángel ‘Cuco’ Peña.

Cost
The initial cost of the park is $4.5 million. The park will link to, but it is different from, another park also currently under construction called Parque Lineal Veredas del Labrador. In addition, there are plans to extend Parque Ecologico southward to connect to Parque de la Ceiba.

Features
The park will have an amphitheater with room for 672 people, a waving path, two pavilions for exhibitions, and a 466-feet artificial river. The park will link to Parque Lineal Veredas del Labrador and to Parque Julio Enrique Monagas.

Signature project
Parque Ecológico Urbano is a project of Ponce Mayor María Meléndez Altieri. She has called the construction of the park one of the five "signature" projects of her administration.

Servo bandwidth. Servo bandwidth is the maximum trackable sinusoidal frequency of amplitude A, with tracking achieved at or before 10% of A amplitude is reached. The servo bandwidth indicates the capability of the servo to follow rapid changes in the commanded input. It is usually specified as a frequency in Hertz or radian/sec.

Explanation 

Bandwidth of systems is generally defined to be the frequency at which the system's amplitude is  times the signal amplitude. But if we apply same logic to servo systems it is difficult to analyze and develop a system to a sufficiently accurate specification. This is because of ambiguity with regard to frequency at which the amplitude should go to .

A simple and sound definition can be sought regarding this.
Let us say we want to design a position servo control system with following specifications:
 Bandwidth:  10 Hz
 Allowed amplitude range : ± 50°

The above definition is not enough to design a practical control system. The definitions above have inherent problems with regard to what amplitude the manufacturer should take to design the servo with 10 Hz bandwidth.
If the manufacturer takes the amplitude to be ±20° and rise time for this amplitude to be 0.025 sec (10 Hz sinusoid)
and some other manufacturer takes amplitude to be ±50°, the acceleration requirements calculated by two will be very different.

This leads us to understand that giving servo bandwidth alone with no amplitude specification is almost useless. Also defining the bandwidth as per normal bandwidth definition does not help (ambiguity with regard to frequency at which the amplitude should go to .

Arkadi Nemirovski. Arkadi Nemirovski (born March 14, 1947) is a professor at the H. Milton Stewart School of Industrial and Systems Engineering at the Georgia Institute of Technology.  He has been a leader in continuous optimization and is best known for his work on the ellipsoid method, modern interior-point methods and robust optimization.

Biography
Nemirovski earned a Ph.D. in Mathematics in 1974 from Moscow State University and a Doctor of Sciences in Mathematics degree in 1990 from the Institute of Cybernetics of the Ukrainian Academy of Sciences in Kiev. He has won three prestigious prizes: the Fulkerson Prize, the George B. Dantzig Prize, and the John von Neumann Theory Prize.
He was elected a member of the U.S. National Academy of Engineering (NAE) in 2017 "for the development of efficient algorithms for large-scale convex optimization problems", and the U.S National Academy of Sciences (NAS) in 2020. In 2023, Nemirovski and Yurii Nesterov were jointly awarded the 2023 WLA Prize in Computer Science or Mathematics "for their seminal work in convex optimization theory, including the theory of self-concordant functions and interior-point methods, a complexity theory of optimization, accelerated gradient methods, and methodological advances in robust optimization."

Academic work
Nemirovski first proposed mirror descent along with David Yudin in 1983.

His work with Yurii Nesterov in their 1994 book is the first to point out that the interior point method can solve convex optimization problems, and the first to make a systematic study of semidefinite programming (SDP). Also in this book, they introduced the self-concordant functions which are useful in the analysis of Newton's method.

Voluson 730. The Voluson 730 is a diagnostic ultrasound machine known for its 3D and 4D imaging in obstetric and gynecological applications.

Early development 
The Voluson 730 was built upon technology developed in the 1980s by Kretztechnik, a company in Austria. Medison, an ultrasound manufacturer in South Korea purchased the Voluson line from Kretz and further developed it into the Voluson 530, then the Voluson 730.

Development by General Electric 
General Electric later purchased the Voluson 730 from Medison and continued to develop it, releasing it in May 2002 as Revision 1.05. Versions previous to 1.05 were produced by Medison. GE gave the Voluson 730 a distinctive industrial design based upon a circular work area colored blue, making it stand out considerably from other more staid looking designs of the time. GE continued to improve the Voluson 730 developing it up to Revision: BT08. GE ran ads heavily promoting the Voluson 730's 4D "babyface" capabilities and making it one of the most widely known ultrasound machines in the OB/GYN field. As of October 2011, GE still produces the Voluson 730 though it has created several upgraded successors such as the Voluson E6, Voluson E8, Voluson S6, and S8.

Versions 
The Voluson 730 was produced by GE in Professional and Expert versions. The Expert added additional features not found on the Pro version, most notable an extra touchscreen LCD used for navigation.

File integrity monitoring. File integrity monitoring (FIM) is an internal control or process that performs the act of validating the integrity of operating system and application software files using a verification method between the current file state and a known, good baseline.  This comparison method often involves calculating a known cryptographic checksum of the file's original baseline and comparing with the calculated checksum of the current state of the file. Other file attributes can also be used to monitor integrity.

Generally, the act of performing file integrity monitoring is automated using internal controls such as an application or process. Such monitoring can be performed randomly, at a defined polling interval, or in real-time.

Security objectives
Changes to configurations, files and file attributes across the IT infrastructure are common, but hidden within a large volume of daily changes can be the few that impact file or configuration integrity. These changes can also reduce security posture and in some cases may be leading indicators of a breach in progress. Values monitored for unexpected changes to files or configuration items include: 
 Credentials
 Privileges and security settings
 Content
 Core attributes and size
 Hash values
 Configuration values

Compliance objectives 
Multiple compliance objectives indicate file integrity monitoring as a requirement. Several examples of compliance objectives with the requirement for file integrity monitoring include: 
 PCI DSS - Payment Card Industry Data Security Standard (Requirement 11.5)
 SOX - Sarbanes-Oxley Act (Section 404)
 NERC CIP - NERC CIP Standard (CIP-010-2)
 FISMA - Federal Information Security Management Act (NIST SP800-53 Rev3)
 HIPAA - Health Insurance Portability and Accountability Act of 1996 (NIST Publication 800-66)
 SANS Critical Security Controls (Control 3)

Sandlin Bug. The Sandlin Bug (Basic Ultralight Glider) is an American biplane, cable-braced, single-seat, ultralight glider that was designed by Mike Sandlin and is provided in the form of technical drawings for amateur construction.

Design and development

The Bug first flew in February 1999. The aircraft was designed to be an inexpensive and easy to fly three axis controlled aircraft similar to a primary glider, although the designer terms it an airchair. The Bug has an empty weight of under  and so qualifies to be operated under the United States FAR 103 Ultralight Vehicles regulations. The aircraft is made available as technical drawings, not plans, to allow potential builders to study them. Sandlin makes his computer assisted design drawings available free of charge as downloads in .dxf, .dwf and .gif formats and has explicitly released them to the public domain. The Bug 4 drawings comprise 66 sheets. The designer considers his aviation activities a hobby only.

The aircraft is made from bolted together aluminium tube, braced with steel cables and covered with heat shrunk Dacron fabric. Its  span wing uses V-shaped interplane struts. Controls are conventional three axis, with the ailerons and elevator controlled by a center stick and rudder controlled by pedals. The landing gear is a fixed monowheel gear. The pilot sits on an open cockpit seat without a windshield and is secured with a four-point harness. The aircraft is designed to be car-top transportable and can be assembled by one person.

The Bug is designed to be launched by aerotow behind an ultralight aircraft, auto-tow, winch-launch or by rolling it down a slope. It is flown for soaring and is not recommended for aerobatics.

Variants
Bug 2
Initial version, drawings no longer available.
Bug 4
Improved version, drawings still available.

Signal analyzer. A signal analyzer is an instrument that measures the magnitude and phase of the input signal at a single frequency within the IF bandwidth of the instrument. It employs digital techniques to extract useful information that is carried by an electrical signal. In common usage the term is related to both spectrum analyzers and vector signal analyzers.  While spectrum analyzers measure the amplitude or magnitude of signals, a signal analyzer with appropriate software or programming can measure any aspect of the signal such as modulation. Today’s high-frequency signal analyzers achieve good performance by optimizing both the analog front end and the digital back end.

Theory of operation

Modern signal analyzers use a superheterodyne receiver to downconvert a portion of the signal spectrum for analysis. As shown in the figure to the right, the signal is first converted to an intermediate frequency and then filtered in order to band-limit the signal and prevent aliasing.  The downconversion can operate in a swept-tuned mode similar to a traditional spectrum analyzer, or in a fixed-tuned mode.  In the fixed-tuned mode the range of frequencies downconverted does not change and the downconverter output is then digitized for further analysis.  The digitizing process typically involves in-phase/quadrature (I/Q) or complex sampling so that all characteristics of the signal are preserved, as opposed to the magnitude-only processing of a spectrum analyzer.  The sampling rate of the digitizing process may be varied in relation to the frequency span under consideration or (more typically) the signal may be digitally resampled.

Typical usage
Signal analyzers can perform the operations of both spectrum analyzers and vector signal analyzers.  A signal analyzer can be viewed as a measurement platform, with operations such as spectrum analysis (including phase noise, power, and distortion) and vector signal analysis (including demodulation or modulation quality analysis) performed as measurement applications.  These measurement applications can be built into the analyzer platform as measurement firmware or installed as changeable application software.
