[Correspondence originally sewn into the front of Volume 1], 1771-1783

This folder contains three letters originally sewn to the front inside cover of Volume 1 of Sewall's bound lectures (HUG 1782 Box 3). A fourth letter is still glued to the inside front cover and listed with the volume. The three letters consist of a letter from B. Kennicott to Stephen Sewall, May 14, 1771 and two letters written in French from Antoine Court de Gébelin to Stephen Sewall, one written on March 3, 1780, and the second received on November 18, 1783. The letter from Benjamin Kennicott acknowledges Sewall's letter to him and offers instructions for paying for a subscription to Kennicott's work. A portion of the missing text from Box 1 can be found in this folder.

DESIGN OF A MINIATURIZED SOP INTEGRATED GNSS RF FRONT-END MODULE

Navigation devices used to be bulky and expensive and were not widely commercialized for personal use. Nowadays, all useful electronic devices are turning into being handheld so that they can be conveniently used anytime and anywhere. One can claim that almost any mobile phone, used today, has quite strong navigational capabilities that can efficiently work anywhere in the globe. No matter where you are, you can easily know your exact location and make your way smoothly to wherever you would like to go. This couldn’t have been made possible without the existence of efficient and small microwave circuits responsible for the transmission and reception of high quality navigation signals. This thesis is mainly concerned with the design of novel highly miniaturized and efficient filtering components working in the Global Navigational Satellite Systems (GNSS) frequency band to be integrated within an efficient Radio Frequency (RF) front-end module (FEM). A System-on-Package (SoP) integration technique is adopted for the design of all the components in this thesis. Two novel miniaturized filters are designed, where one of them is a wideband filter targeting the complete GNSS band with a fractional bandwidth of almost 50% at a center frequency of 1.385 GHz. This filter utilizes a direct inductive coupling topology to achieve the required wide band performance. It also has very good out-of-band rejection and low IL. Whereas the other dual band filter will only cover the lower and upper GNSS bands with a rejection notch in between the two bands. It has very good inter band rejection. The well-known “divide and conquer” design methodology was applied for the design of this filter to help save valuable design and optimization time. Moreover, the performance of two commercially available ultra-Low Noise Amplifiers (LNAs) is studied. The complete RF FEM showed promising preliminary performance in terms of noise figure, gain and bandwidth, where it out performed other commercial front-ends in these three aspects. All the designed circuits are fabricated and tested. The measured results are found to be in good agreements with the simulations.

Tunisia. Supervising Tunisian Elections by civil society: How to improve it? Arab Citizenship Review No. 7. January 2015

Introduction. On October 26, 2014, Tunisia held its second democratic legislative elections. Participation among more than 5 million registered voters was at about 60%, a relatively good turnout for the country, compared to the 52% voters in 2011. Preliminary results for the 33 constituencies (27 within the country and 6 for expatriates) reveal that secular frontrunner Nidaa Tounes (Call of Tunisia) won around 37% percent of votes while moderate Islamist party Ennahdha, winner of the 2011 elections and leader of Tunisia’s post-revolution government, received 27% of votes. Other parties with notable percentages are the Free Patriotic Union (French: UPL) with 4.4% and the leftist party, Popular Front, with 3.7%. Legislative were immediately followed by two round presidential elections the first one held on November 23, the second one after one month. Conversely to what was expected, people were more attracted by presidential elections even though president has notably less prerogatives than the parliament: representing the state, he is mainly responsible for determining the general state policies in the domains of defense, foreign relations and national security (article 76.) This paradox is ascribed to national imaginary more confident in a “Zaïm” (leader) rather than a collective institution such as a parliament. The turnout was at about 64% within the national 27 constituencies. Out of 70 candidates (including 5 female), 27 (with only one female) met the legal requirements to run for the presidency. The result confirms the legislative trend and Beji Caid Essebsi, leader of Nidaa, was proclaimed the third President of Tunisia. He gained 39.46% of the votes at the first round elections. Essebsi was followed by Moncef Marzouki who received an unexpected score (33.43%) at the first round, thanks to the support of Ennahdha audience and to an active and insistent campaign focused on the idea that revolution is threatened by old regime guard “come-back.” Rewarded for his long militant live, the extreme leftist Hamma Hammami in a new look gained 7,8% of the votes while the new comer Slim Riahi received 5,5% despite rumors circulating on his personal reputation. Notably, Kalthoum Kennou gained 0,55% (18.287 votes) but listed eleventh out of 27.

Unified European Front: The Road towards a European Unitary Patent. EU Centre Singapore Working Paper No. 21, March 2014

For over forty years, European countries have held numerous conferences and signed multiple international agreements aimed at either creating a unitary patent which will be valid in all European countries upon issuance or establishing a specialized European court with jurisdiction over patents. This paper first outlines the need for a unitary patent in the European Union and then chronicles the measures taken to support and milestones toward the creation of a European-wide unitary patent system. The paper then discusses the few problems and pitfalls that have prevented European countries from coming to an agreement on such a patent system. Finally, the paper considers the closely related agreements of ‘Unitary Patent Package’, the challenges facing these agreements and examines if it would finally result in an EU Unitary patent system that benefits one and all.

Ukraine on the financial front – the problem of Ukraine’s foreign public debt. OSW COMMENTARY NUMBER 178|05.08.2015

One of the key challenges that Ukraine is facing is the scale of its foreign debt (both public and private). As of 1st April it stood at US$ 126 billion, which is 109.8% of the country’s GDP. Approximately 45% of these financial obligations are short-term, meaning that they must be paid off within a year. Although the value of the debt has fallen by nearly US$ 10 billion since the end of 2014 (due to the private sector paying a part of the liabilities), the debt to GDP ratio has increased due to the recession and the depreciation of the hryvnia. The value of Ukraine’s foreign public debt is also on the rise (including state guarantees); since the beginning of 2015 it has risen from US$ 37.6 billion to US$ 43.6 billion. Ukraine does not currently have the resources to pay off its debt. In this situation a debt restructuring is necessary and this is one of the top priorities for the Ukrainian government as well as for the International Monetary Fund (IMF) and its assistance programme. Without this it will be much more difficult for Ukraine to overcome the economic crisis.

Putting Up a Big Front: Car Design and Size Affect Road-Crossing Behaviour

Previous research suggests that people tend to see faces in car fronts and that they attribute personality characteristics to car faces. In the present study we investigated whether car design influences pedestrian road-crossing behaviour. An immersive virtual reality environment with a zebra crossing scenario was used to determine a) whether the minimum accepted distance for crossing the street is larger for cars with a dominant appearance than for cars with a friendly appearance and b) whether the speed of dominant-looking cars is overestimated as compared to friendly-looking cars. Participants completed both tasks while either standing on the pavement or on the centre island. We found that people started to cross the road later in front of friendly-looking low-power cars compared to dominant-looking high-power cars, but only if the cars were relatively large in size. For small cars we found no effect of power. The speed of smaller cars was estimated to be higher compared to large cars (size-speed bias). Furthermore, there was an effect of starting position: From the centre island, participants entered the road significantly later (i. e. closer to the approaching car) and left the road later than when starting from the pavement. Similarly, the speed of the cars was estimated significantly lower when standing on the centre island compared to the pavement. To our knowledge, this is the first study to show that car fronts elicit responses on a behavioural level.

Tab. 1: Rates of advance of the frontal push-moraines of 19 lobes in front of an approx. 4.5 km long margin of the Kötlujökull

In the last years masses of ice, about 5 km long, have been protruding from the lowest part of an advancing glacier margin of the Kötlujökull in Southern Iceland. In the summer of 1983, they appeared as sediment-covered lobes, 10-60 m long, bordering the glacier rnargin like agarland. 1 to 3 push-rnoraines without ice core, rnostly sickle-shaped, occured first in the frontal parts of the lobes: behind thern came several ice-cored moraines with heights of up to several metres. The active ice in front of the precipice of the glacier is called the "glacier-foot" in this paper. The digging out of 9 lobes and the measuring of the advance of 19 lobes showed that in most cases this glacierfoot had split up at its distal end into several plate- or stem-shaped pieces of ice which were situated one upon the other, separated by moraine deposits and proceeding irregularly into the foreland at the rate of several mm/h, The sometimes different rate of advance in the same lobe and different rates of advanee in adjoining lobes (some being entirely inactive) point to a type of rnovement which is independent of the general advance of the glacier. Research in the winter of 1983/84 showed less activity in 3 examined lobes, but the activity had not ceased. The advancement of the lower parts of the glacier-foot into and across the sands of the foreland implies the following genesis of pushmoraines: Shoving off a plate of sand, folding it and pushing it over the foreland at average rates of up to 7,2 mm/h, according to the investigations in thc summer of 1983. At a certain stage of the folding process, new folds begin to develop in front of the old, and the old folds are shifted onto the backslope of thc folds in front of them until they are completely unired. In this way, "püe-moraines" arise, which become higher and higher. They include two or more folds declining towards the glacier. Systems of small moraines presumably of the same genesis occur on old moraine areas in front of the Kötlujökull. The possible cause of formation of a glacier-foot is discussed, and the moraines of the Kötlujökull are compared with certain pleistocene push-moraines.

Surface velocity fields, digital elevation models and ice front positions derived from multi-mission SAR remote sensing data at Sjögren Inlet glaciers, Antarctic Peninsula

Substantial retreat or disintegration of numerous ice shelves have been observed on the Antarctic Peninsula. The ice shelf in the Prince Gustav Channel retreated gradually since the late 1980's and broke-up in 1995. Tributary glaciers reacted with speed-up, surface lowering and increased ice discharge, consequently contributing to sea level rise. We present a detailed long-term study (1993-2014) on the dynamic response of Sjögren Inlet glaciers to the disintegration of Prince Gustav Ice Shelf. We analyzed various remote sensing datasets to observe the reactions of the glaciers to the loss of the buttressing ice shelf. A strong increase in ice surface velocities was observed with maximum flow speeds reaching 2.82±0.48 m/d in 2007 and 1.50±0.32 m/d in 2004 at Sjögren and Boydell glaciers respectively. Subsequently, the flow velocities decelerated, however in late 2014, we still measured about two times the values of our first measurements in 1996. The tributary glaciers retreated 61.7±3.1 km² behind the former grounding line of the ice shelf. In regions below 1000 m a.s.l., a mean surface lowering of -68±10 m (-3.1 m/a) was observed in the period 1993-2014. The lowering rate decreased to -2.2 m/a in recent years. Based on the surface lowering rates, geodetic mass balances of the glaciers were derived for different time steps. High mass loss rate of -1.21±0.36 Gt/a was found in the earliest period (1993-2001). Due to the dynamic adjustments of the glaciers to the new boundary conditions the ice mass loss reduced to -0.59±0.11 Gt/a in the period 2012-2014, resulting in an average mass loss rate of -0.89±0.16 Gt/a (1993-2014). Including the retreat of the ice front and grounding line, a total mass change of -38.5±7.7 Gt and a contribution to sea level rise of 0.061±0.013 mm were computed. Analysis of the ice flux revealed that available bedrock elevation estimates at Sjögren Inlet are too shallow and are the major uncertainty in ice flux computations. This temporally dense time series analysis of Sjögren Inlet glaciers shows that the adjustments of tributary glaciers to ice shelf disintegration are still going on and provides detailed information of the changes in glacier dynamics.
