The Derfflinger class was a class of three battlecruisers of the German Imperial Navy. The ships were ordered for the 1912 to 1913 Naval Building Program of the German Imperial Navy as a reply to the Royal Navy's three new Lion-class battlecruisers that had been launched a few years earlier. The preceding Moltke class and the incrementally improved Seydlitz represented the end of the evolution of Germany's first generation of battlecruisers. The Derfflinger class boasted considerable improvements, including a larger primary armament, all of which was mounted on the centerline, eliminating the restricted arc of the amidships turret. The ships were also larger than the preceding classes. However, the Derfflinger class used a similar...

High Quality Content by WIKIPEDIA articles! The term derringer is a genericized misspelling of the last name of Henry Deringer, a famous maker of small pocket pistols in the 1800s. Many copies of the original Philadelphia Deringer pistol were made by other gun makers worldwide, and the name was often misspelled; this misspelling soon became a generic term for any pocket pistol. The original Deringer pistol was a single-shot muzzleloading pistol; with the advent of cartridge firearms, pistols began to be produced in the modern form still known as a derringer. A derringer is generally the smallest usable handgun of a given caliber. They were frequently used by women, because they are easily concealable in a purse or as a stocking gun....

High Quality Content by WIKIPEDIA articles! A derrick is a lifting device composed of one mast or pole which is hinged freely at the bottom. It is controlled by lines (usually four of them) powered by some means such as man-hauling or motors, so that the pole can move in all four directions. A line runs up it and over its top with a hook on the end, like with a crane. It is commonly used in docks and onboard ships. Some large derricks are mounted on dedicated vessels, and are often known as "floating derricks". The device was named for its resemblance to a type of gallows from which a hangman's noose hangs. The derrick type of gallows in turn got its name from Thomas Derrick, an English executioner from the Elizabethan era. Данное...

Products are designed by someone to be perceived by someone. Design Semiosis was originally presented as a Doctoral Thesis for the Dept. of Machine Design at the Royal Institute of Technology, Stockhom, Sweden. It contains a concept that speaks about the synthesis of physical products by a human designer. The foundations of this concept are the semiotics of Charles S. Peirce and the sign theories of Charles W. Morris. To these are added ideas about the nature of product properties. Traditional research in product design typically suggests analytical acts in synthesis, based on empirical research. Design Semiosis presents an application of abduction to propose that the designers' perception of a products' properties is the natural driver...

The main purpose of this book is to introduce the reader to the fundamental analytical concepts of the design of minimum-weight structures. This subject, more broadly termed structural optimization, is currently enjoying great interest in the engineering research. The goal of structural optimization is to create finite-element based iterative modeling systems, which will enable the establishment early in any design of the structural layout required for minimum-weight design. Once this layout is known, the remaining detailed design engineering can follow well established steps. To emphasize that the difficult task of layout, or topology is being undertaken, the topic is often referred to as topological structural optimization (TSO). It is...

Microstrip edge coupled ?lters perform well as bandpass ?lters with a decent skirt rate. Coplanar waveguide (CPW) ?lters have been developed because of the good isolation they provide. Development of tuning techniques for these passive ?lters is becoming increasingly necessary to improve the robustness and reliability of microwave receiver designs. For example, in a high Q ?lter, a slight shift of the center frequency in a fabricated ?lter results in a very large change in the resulting gain at the frequencies of interest. This book explains the design of tunable microstrip edge-coupled filters and introduces three new tuning techniques for edge coupled filters. MATLAB codes for analyzing tunable edge-coupled filters are also provided....

Design A- 150, also known as the Super Yamato class,[A 1] was a Japanese plan for a class of battleships. Begun in 1938–39, the design was mostly complete by 1941. However, so that a demand for other types of warships could be met, all work on Design A-150 was halted and no keels were laid. Authors William H. Garzke and Robert O. Dulin have argued that Design A- 150 would have been the "most powerful battleships in history"[3] because of the massive size of their main battery of six 510 mm (20 in) guns as well as numerous smaller caliber weapons.

Fracture to the neck of femur is frequently stabilised with a hip screw system, however the host bone is often weak or osteoporotic. This causes premature failure of the system, commonly by cut-out of the lag screw through the head of the femur. While augmentation of the fixation with bone cement improves the holding power and decreases failure rate, current methods of administering the cement are messy and inaccurate. This project proposes a lag screw design which allows for direct injection of the cement, via the lag screw itself, after the screw has been inserted and correctly positioned in the femur. A method is also suggested to reduce the risk of cement leakage into the joint space when the guide wire has punctured the head of the...

Chapter 2 of this work brings together a full set of analytical tools to generate structural layouts which satisfy dual-material optimality conditions. Chapter 3 of the dissertation is concerned with methods to suppress local and global instability of least-weight structures. Perforated webs placed between structural members, structural member shape optimization and light-weight foam inserts are methods investigated in the research to address the instability problems. Simply supported least-weight arch beams were designed and mechanically tested. The experimental results were compared with FEA. In Chapter 4 matrix operator methods used to generate optimal layouts with straight boundaries were extended to include curved boundaries. A...

Optimization is the act of obtaining the best result under given circumstances. In design, construction, and maintenance of any engineering system, engineers have to take many technological and managerial decisions at every stage. The ultimate goal of all such decisions is either to minimize the efforts required or to maximize the desired benefit. Effort required or the benefit desired in any practical situation can be expressed as a function of certain decision variables. This book therefore provides the ground rules in understanding the techniques and methodologies, complete with case studies, for hands on learning for the product development. This includes a summary of the basics of CAD modelling, optimization (topology, structural,...

The state-of-the-art variable message sign (VMS) systems have been widely used as a crucial means in the daily traffic environment to promote safe and efficient driving on highways. In addition, these overhead mounted VMSs play an important role in the Intelligent Transportation System (ITS) by displaying real-time information and advice about roadway and traffic conditions. Thus, a properly designed and displayed message on VMS is especially important to a motorist who has to detect, comprehend, and act on signage information while being occupied with the driving task. To this end, this book proposes a comprehensive human factors study, incorporating three approaches: driver questionnaire surveys, lab experiments, and field studies, to...

Modulation code for optical recording systems have been concentrated on the combined DC-free and runlength-limited (RLL) code, in short DCRLL code. However, the design of high rate DCRLL code satisfying all of two constraints is far from obvious. Certainly, if channel is not free of errors, it is pointless to feed the sequences only satisfying RLL constraints.The weakly constrained coding scheme can accomplish the higher rate while it may relatively cause error in channel. The problem can be solved by designing the code with error correction capability. In this dissertation, in order to accomplish the above goals, low-density parity-check coded multimode code (LDPCCMC) and selection criteria are developed. The error control of LDPCCMC is...

This book reports the development of an integrated low-power readout circuit for a capacitive sensor with 40 - 60 pF basic capacitance. The sensor is used to detect screw loosening in an osteosynthesis measurement system. To ensure detection of screw loosening the readout circuit must be able to measure capacitance changes of at least 0.25 pF. Several readout techniques for capacitive sensors are investigated and evaluated for this application. Finally two types are developed and simulated, a Wien-bridge oscillator and a switched capacitor (SC) capacitance to voltage (C/V) converter. The oscillator is simulated with Cadence in a 0.35 µm triple-well, 4-metal, and double poly CMOS process from austriamicrosystems. The Wien-bridge is...

As part of an accelerator based cargo inspection system, studies were made to develop a cabinet safe system by optimization of the beam optics of microwave linear accelerators working on the S-band and standing wave pi/2 mode. Measurements, modeling and simulations of the main subsystems were done and a multiple solenoidal system was designed. This cabinet safe system based on a multiple solenoidal system minimizes the radiation field generated by the low efficiency of certain microwave accelerators by optimizing the RF waveguide system and by also trapping secondaries generated in the accelerator head. The electron gun was also studied and software for its right mechanical design and for its optimization was developed as well. The...
