In this report the gas chromatography column was fabricated base on micro electro mechanical system (MEMS) technology. It tries to find an equilibrium point which can fast detect CWA stimulants with efficient column separation. Under deep reactive-ion etching (DRIE) process, a 1m length, 90 um thickness and 300 um height which form 3:1high-aspect-ratio, MEMS-based silicon GC column was fabricated. The GC column was coated with 95%Methyl 5% Phenyl Polysilozane (DB-5) as the stationary phase. Dimethyl methyl phosphonate (DMMP), Triethyl phosphate (TEP) and Methy salicylate were used for CWA simulations. All of these three samples can be separated less than 90s with reasonable column efficiency.

Excessive dependence on information and communication technologies, cloud infrastructures, big data analytics, data-mining and automation in decision making poses grave threats to business and economy in adversarial environments. Adversarial machine learning is a fast growing area of research which studies the design of Machine Learning algorithms that are robust in adversarial environments. This paper presents a comprehensive survey of this emerging area and the various techniques of adversary modelling. We explore the threat models for Machine Learning systems and describe the various techniques to attack and defend them. We present privacy issues in these models and describe a cyber-warfare test-bed to test the effectiveness of the various attack-defence strategies and conclude with some open problems in this area of research.</p><p> </p></div></div></div>

Around 700 BCE, a new military formation called the phalanx was established in ancient Greece: a tight column of heavy infantry carrying long spears, or pikes, used in a single prong of attack. Later, in the battle of Marathon described by Herodotus, the Greeks learned the advantages of multipronged attacks, a strategy still used in modern warfare. Is the immune system similar in its approach to combating pathogens or tumors?

Full textAbstract:
The nursing work of the First World War is usually associated with the trench warfare of the Western Front. Nurses were based within fairly permanent casualty clearing stations and field hospitals, and patients were moved “down the line” to base hospitals, and then to convalescent hospitals “at home.” The nurses and volunteers who worked on the Eastern Front and offered their services to the letuchka or “flying columns” of the Russian medical services had a very different experience. They worked with highly mobile units, following a rapidly moving “front line.” The diaries of three British (one Anglo-Russian) nurses who worked alongside Russian nursing sisterhoods in three different flying columns—Violetta Thurstan (Field Hospital and Flying Column), Florence Farmborough (With the Armies of the Tsar) and Mary Britnieva (One Woman’s Story)—stand as an important corpus of nursing writing. Written in a highly romantic style, they take up similar themes around their work on the Eastern Front as a heroic journey through a dreamlike landscape. Each nurse offers a portrayal of the Russian character as fine and noble. The most important themes deal with the romance of nursing itself, in which nursing work is portrayed as both character-testing and a highly spiritual pursuit.

ABSTRACT
Sonic Layer Depth is the vertical distance from surface to the depth where the speed of sound reach it’s local maximum. Global Navy as well as Indonesan Navy operates in this kind of layers on a daily basis, wether it be in an anti submarine warfare operation through its ships and aircrafts or in an anti-surface warfare operation waged by its submarines. For the navy, the importance of knowing the exact value of the SLD is because it determines the minimum cut off frequency and sound wave propagation above which sound tends to be trapped and below which a shadow zone exist. This has a direct impact on where the navy operates its sensors and places its platforms in the water column. The best way to estimate SLD is by performing own measurement on the ocean using instrument such as expendable bathytermographs, which can be relatively expensive and time consuming for an operational navy ships, furthermore such measurement may be impractical in the case of mission planning or emergencies. Dedicated oceanography survey for the purpose of science and defense is relatively scarce due to prioritization concerning to the budget available resulting lack of time series in situ CTD observation which cover full annual cycle variation in Indonesia waters. Banda Indonesia Through Flow Dynamic Experiment (BIDE) is multi institution and bilateral oceanography experiment led by Indonesian scientist which utilizes argo float to perform in situ CTD measurement in Banda Sea to get an adequate time series data that cover full annual cycle variation. The dataset is publicly available so defense community as well may utilize the data for defense interest such as sonic layer depth variation analysis in Banda Sea.

Full textAbstract:
Att mäta och värdera motståndarens och sin egen krigföringsförmåga är angeläget i alla typer av militära konflikter. Svensk doktrin presenterar pelarmodellen som ett verktyg för detta. Med tanke på att den svenska försvarsmakten genomgått stora förändringar sedan pelarmodellen först introducerades i de svenska doktrinerna är det möjligt att den inte fyller sin funktion i de typer av militära konflikter som Sverige nu deltar i. I denna uppsats genomförs en teoriprövande studie av modellen i syfte att undersöka om den fortfarande är tillämpbar i sin befintliga form. Modellen prövas mot teorier av David Galula och John Warden vilka beskriver två typer av militära operationer som den svenska försvarsmakten deltar eller nyligen har deltagit i. Undersökningen visar att de faktorer som ingår i pelarmodellen också förekommer i Galulas och Wardens teorier samt att pelarmodellen fortfarande är tillämpbar i sin befintliga form. Dock kan modellen tolkas på en mängd olika sätt och betydelsen av dess ingående faktorer skiljer sig för olika typer av konflikter. För att öka användbarheten krävs kompletterande förklaringar kring modellen och begreppet krigföringsförmåga samt ett förtydligande av hur de fysiska, konceptuella och moraliska faktorerna är beroende av varandra.To measure and evaluate the opponent’s and your own warfare capability is essential in all types of military conflicts. Swedish doctrine presents the column model as a tool for this. Given that the Swedish armed forces have undergone major changes since the column model was first introduced in the Swedish doctrines, it is possible that it doesn’t fulfill its role in the types of military conflicts that Sweden is now participating in. In this paper it is carried out a theory testing study of the model in order to study if it is still applicable in its existing form. The model is tested toward the theories of David Galula and John Warden which describes two types of military operations that the Swedish armed forces are or have recently participated in.The study shows that the factors included in the column model also are present in Galula’s and Warden's theories and that the column model still applies in its existing form. However, the model can be interpreted in a variety of ways and the importance of its constituent elements are different for different types of conflicts. To enhance the usability additional explanations about the model and the concept of warfare capability is needed as well as a clarification of how the physical, conceptual and moral factors are interdependent.

Full textAbstract:
L’esercito italiano e la conquista della Catalogna (1808-1811)
Uno studio di Military Effectiveness nell’Europa napoleonica
Settori scientifico-disciplinari SPS/03 – M-STO/02
La ricerca ha lo scopo di ricostruire e valutare l’effettività militare dell’esercito italiano al servizio di Napoleone I. In primo luogo attraverso un’analisi statistica e strategica della costruzione, e del successivo impiego, dell’istituzione militare del Regno d’Italia durante gli anni della sua esistenza (1805-14); successivamente, è stato scelto un caso di studi particolarmente significativo, come la campagna di Catalogna (1808-11, nel contesto della guerra di Indipendenza spagnola), per poter valutare il contributo operazionale e tattico dei corpi inviati dal governo di Milano e la loro integrazione con l’apparato militare complessivo del Primo Impero.
La tesi ha voluto rispondere alla mancanza di studi sul comportamento in guerra dell’esercito italiano e, allo stesso tempo, introdurre nella storiografia militare italiana la metodologia di studi, d’origine anglosassone e ormai di tradizione trentennale, di Military Effectiveness.
La ricerca si è primariamente basata, oltre che sulla copiosa memorialistica a stampa italiana e francese, sulla documentazione d’archivio della Secrétairerie d’état impériale (Archives Nationales di Pierrefitte-sur-Seine, Parigi), del Ministère de la Guerre francese (Service historique de la Défence, di Vincennes, Parigi) e del Ministero della Guerra del Regno d’Italia (Archivio di Stato di Milano).
Dal punto di vista dei risultati è stato possibile verificare come l’esercito italiano abbia rappresentato, per Bonaparte, uno strumento duttile e di facile impiego, pur in un contesto di sostanziale marginalità numerica complessiva di fronte alle altre (e cospicue) forze messe in campo da parte dell’Impero e dei suoi altri Stati satellite e alleati. Per quanto riguarda la campagna di conquista della Catalogna è stato invece possibile appurare il fondamentale contributo dato dal contingente italiano, sotto i punti di vista operazionale e tattico, per la buona riuscita dell’invasione; questo primariamente grazie alle elevate caratteristiche generali mostrate dallo stesso, ma anche per peculiarità disciplinari e organizzative che resero i corpi italiani adatti a operazioni particolarmente aggressive.The Italian Army and the Conquest of Catalonia (1808-1811) A Study of Military Effectiveness in Napoleonic Europe Academic Fields and Disciplines SPS/03 – M-STO/02 The research has the purpose of reconstruct and evaluate the military effectiveness of the Italian Army existed under the reign of Napoleon I. Firstly through a statistic and strategic analysis of the development, and the following deployment, of the military institution of the Kingdom of Italy in the years of its existence (1805-14). Afterwards, a particularly significant case study was chosen, as the campaign of Catalonia (1808-11, in the context of the Peninsular War), in order to assess the operational and tactical contribution of the regiments sent by the Government of Milan and their integration in the overall military apparatus of the First Empire. The thesis wanted to respond to the lack of studies on the Italian army’s behavior in war and, at the same time, to introduce the methodology of the Military Effectiveness Studies (of British and American origin and, by now, enriched by a thirty-year old tradition) in the Italian historiography. The research is primarily based, besides the numerous memoirs of the Italian and French veterans, on the archive documentation of the Secrétairerie d’état impériale (Archives Nationales of Pierrefitte-sur-Seine, Paris), of the French Ministère de la Guerre (Service historique de la Défence, of Vincennes, Paris) and of the Italian Ministero della Guerra (Archivio di Stato di Milano). About the results, it has been verified how the Italian army has become a flexible and suitable instrument for Bonaparte, albeit in a context of substantial overall numerical marginality in comparison to the heterogeneous forces available to the Empire and its others satellites and allied states. Regarding the campaign of Catalonia, instead, it was possible to ascertain the fundamental contribution of the Italian regiments, in an operational and tactical perspective, for the success of the invasion. This was primarily due to the excellent general characteristics shown by the expeditionary force, but also to disciplinary and organizational peculiarities that have made the Italian corps suitable for particularly aggressive operations.

This chapter focuses on William Clark, who replaced Brigadier General Benjamin Howard in command at Saint Louis. Major General William Henry Harrison suggested Clark, whom he knew from the days when they had both served under “Mad Anthony” Wayne. Son of a prominent Virginia family, and the younger brother of George Rogers Clark—the conqueror of Kaskaskia and Vincennes—William had followed his elder brother into the army. William was already experienced in Indian warfare when he commanded a column of riflemen at the battle of Fallen Timbers (1794), and the next year he was present when the Treaty of Greenville brought the Indian war to a close. After the treaty, Clark resigned from the army and occupied himself with his private affairs until Meriwether Lewis suggested him as joint commander of the Corps of Discovery.

Full textAbstract:
Advances in undersea technology have made the seabed more accessible to human activity, both civilian and military. All states may emplace military installations and structures on the seabed beyond the territorial sea of other nations for purposes other than exploitation of economic resources. The placement of nuclear weapons and other weapons of mass destruction on the seabed is prohibited by the Seabed Nuclear Arms, although it does not prohibit the use of nuclear weapons in the water column provided they are not affixed to the seabed. Also, the emplacement of sensors and conventional weapons on the ocean floor, like the U.S. Hydra Distributed Undersea Network and Upward Falling Payloads, is not prohibited. The importance of the undersea cable network for both civilian and military communications cannot be overemphasized, but this network remains vulnerable. In peacetime, submarine cables are protected by several international treaties. But in times of armed conflict, belligerents can degrade, damage, or sever submarine cables, or use them to launch cyberattacks. However, attacks on the network could have third-order effects beyond belligerents, affecting neutral states.

In 1996 Colin Gray asked ‘where is the theory of space power? Where is the Mahan for the final frontier?’1 This book answers that question by presenting propositions of spacepower and a strategic analogy of Earth orbit as a cosmic coastline. This book’s spacepower theory shows how to think more constructively and critically about the use of space systems in warfare – satellites, their infrastructure, methods of attacking them, and their influence on modern warfare and strategy. Spacepower theory helps to answer questions like ‘will a war begin or be decided in space?’, ‘how do satellites change the way war is conducted on Earth?’ and ‘what difference can space warfare make on Earth?’ Engaging with these questions has never been so important, as the use and deployment of satellites and space infrastructure – or spacepower – have become essential for modern military and economic power. It underpins and shapes a global web of connectivity and information-based economies. It provides new methods of political–economic development and control for continent-sized states. Space warfare is a realistic prospect because space technologies are at the heart of military weapon systems, intelligence, logistics and economics, and the tools for harassing or disabling satellites are spreading. In short, spacepower and the spectre of space warfare cannot be ignored in international relations (IR) and modern strategy. Spacepower represents a logical extension of the concept of power – however defined – in IR and it ‘consists of capabilities designed to control, deny, exploit, and regulate the use of space’....

Full textAbstract:
Chapter 1 serves as an introductory chapter, exploring the idea of the sea as a legal and strategic space. The concepts of freedom of the seas and sovereignty of the sea dominated the legal debates about the ownership of the seas. In wartime these concepts clashed as neutrals demanded freedom of the seas while belligerents claimed the sovereignty of the sea. The chapter explores the means to control the seas, in particular, blockade, the right of search and capture, and the rule of 1756. When Great Britain reassessed its strategic position in the mid-nineteenth century, it was John C. R. Colomb who emphasized the importance of imperial defence and the protection of trade in a future maritime conflict. The discussion on the effectiveness of economic warfare brought strategic and legal considerations together since both were concerned with the ability to control the sea.

Full textAbstract:
Impact loads from waves on vessels and coastal structures are highly complex and may involve wave breaking, making these changes difficult to estimate numerically or empirically. Results from previous experiments have shown a wide range of forces and pressures measured from breaking and non-breaking waves, with no clear trend between wave characteristics and the localized forces and pressures that they generate. In 2008, a canonical breaking wave impact data set was obtained at the Naval Surface Warfare Center, Carderock Division, by measuring the distribution of impact pressures of incident non-breaking and breaking waves on one face of a cube. The effects of wave height, wavelength, face orientation, face angle, and submergence depth were investigated. A limited number of runs were made at low forward speeds, ranging from about 0.5 to 2 knots (0.26 to 1.03 m/s). The measurement cube was outfitted with a removable instrumented plate measuring 1 ft2 (0.09 m2), and the wave heights tested ranged from 8–14 inches (20.3 to 35.6 cm). The instrumented plate had 9 slam panels of varying sizes made from polyvinyl chloride (PVC) and 11 pressure gages; this data was collected at 5 kHz to capture the dynamic response of the gages and panels and fully resolve the shapes of the impacts. A Kistler gage was used to measure the total force averaged over the cube face. A bottom mounted acoustic Doppler current profiler (ADCP) was used to obtain measurements of velocity through the water column to provide incoming velocity boundary conditions. A Light Detecting and Ranging (LiDAR) system was also used above the basin to obtain a surface mapping of the free surface over a distance of approximately 15 feet (4.6 m). Additional point measurements of the free surface were made using acoustic distance sensors. Standard and high-speed video cameras were used to capture a qualitative assessment of the impacts. Impact loads on the plate tend to increase with wave height, as well as with plate inclination toward incoming waves. Further trends of the pressures and forces with wave characteristics, cube orientation, draft and face angle are investigated and presented in this paper, and are also compared with previous test results.

Military diving operations are routinely conducted in what can be one of the most inhospitable environments on the planet, frequently characterized by zero visibility. The inability to clearly see the immediate operational environment has historically been a serious limitation to manned diving operations — whether the mission is ship husbandry, under water construction, salvage, or scientific research. U.S. Navy diving is an integral part of the nation’s defense strategy with a continuing requirement to conduct manned intervention in the water column. To ensure technical superiority across the entire spectrum of diving operations we must identify, exploit, and de velop technology to advance the state-of-the-art in diving equipment. This can only be achieved by investing in, and supporting, focused research and development with specific goals to further diving capabilities. Under a project sponsored by the Office of Naval Research (ONR) and Naval Sea Systems Command (NAVSEA), the Naval Surface Warfare Center-Panama City Division (NSWC PCD) has de veloped a prototype see-through head-up display system for a U. S. Navy diving helmet — the Divers Augmented Vision Display (DAVD). The DAVD system uses waveguide optical display modules that couple images from a micro display into a waveguide optic, translate the images through a series of internal reflections, finally exiting toward the diver’s eye providing a magnified, see-through virtual image at a specific distance in front of the diver. The virtual images can be critical information and sensor data including sonar images, ship husbandry and underwater construction schematics, enhanced navigation displays, augmented reality, and text messages. NSWC PCD is the U.S. Navy’s leading laboratory for research, development, testing, evaluation, and technology transition of diver visual display systems; with unique facilities for rapid prototyping and manufacturing, human systems integration and extreme environment testing. Along with NSWC PCD, the Navy Experimental Diving Unit (NEDU), and Naval Diving and Salvage Training Center (NDSTC) are co-located tenant commands at the Naval Support Activity Panama City (NSA PC). This paper provides a brief background on the development of diver head-up display systems, waveguide optical display technology, development of the DAVD prototype, results of diver evaluations, and recommendations for accelerated development of this game changing capability.

An immobilised monoclonal antibody (ESN1) was repeatedly used for the preparation of artificial factor IX (FIX) deficient plasma (AND), and subsequent recovery of bound FIX. Column depletion removed >99% of the FIX from plasma, without affecting other clotting factors. Results of FIX assays performed with AND showed excellent correlation (r=0.981) with those using congenital FIX deficient plasma for plasma obtained from normal subjects, from patients on warfarin treatment, and congenitally FIX deficient subjects. Moreover, 70-90% of bound FIX was each time recovered from the ESN1 column in active form by elution with 7 M urea. After concentration and absorbtion of the eluate with protein A Sepharose CL4B, western blotting of non-reduced^ and reduced FIX showed a single major band which co-migrated with conventionally purified FIX. Repeated use of the ESN1 column (>9 times) has not hindered AND preparation or the recovery of bound FIX in active form.
