Principles of the Spin Model Checker

Surrounded as we are by software for personal computers, electronic gadgets and entertainment websites, it is easy to lose sight of the massive amount of software embedded in critical systems. I was surprised when I found out that the computerized systems in modern cars have half a million lines of code, and that electronics account for 25% of their cost and this percentage is forecast to increase.1 Perhaps it is easiest to characterize a critical system as one that must be delivered without one of those infamous “end user license agreements” that disavows liability and requires you to renounce any claim to a guarantee....

Organizational Behavior

People at work in organizations today are part of a new era. The institutions of society and the people who make them work are challenged in many and very special ways. Society at large increasingly expects high performance and high quality of life to go hand-in-hand, considers ethics and social responsibility core values, respects the vast potential of demographic and cultural diversity among people, and accepts the imprint of a globalization on everyday living and organizational competitiveness. In this new era of work and organizations, the body of knowledge we call “organizational behavior” offers many insights of great value....

RAD Studio (Common)

As you develop your application in the IDE, you can compile (or make), build, and run the application in the IDE. All three operations can produce an executable (such as .exe, .dll, .obj, or .bpl). However, the three operations differ slightly in behavior: • Compile (Project Compile) or, for C++, Make ( Project Make) compiles only those files that have changed since the last build as well as any files that depend on them. Compiling or making does not execute the application (see Run). • Build (Project Build) compiles all of the source code in the current project, regardless of whether any source code has changed....

Chapter 4 - Hamming Codes

In the late 1940’s Claude Shannon was developing information theory and coding as a mathematical model for communication. At the same time, Richard Hamming, a colleague of Shannon’s at Bell Laboratories, found a need for error correction in his work on computers. Parity checking was already being used to detect errors in the calculations of the relay-based computers of the day, and Hamming realized that a more sophisticated pattern of parity checking allowed the correction of single errors along with the detection of double errors. The codes that Hamming devised, the single-error-correcting binary Hamming codes and their single-error-correcting, double-error-detecting extended...

THROUGH THE YELLOWSTONE PARK TO FORT CUSTER

It was about 8.30 A. M. before the boat was found, some travellers having removed it from the place where Baronette had cachéd it. A half hour sufficed to wrap a tentcover neatly around the bottom and to tack it fast on the thwarts. Then two oblongs of flat wood were nailed on ten feet of pine-stems and called oars; and, so equipped, we were ready to start. We had driven or ridden hundreds of miles over a country familiar to any one who chooses to read half a dozen books or reports; but, once across the Yellowstone, we...

B-12’s MOON GLOW

Among the metal-persons of Phobos, robot B-12 held a special niche. He might not have been stronger, larger, faster than some … but he could be devious … and more important, he was that junkyard planetoid’s only moonshiner. I AM B-12, a metal person. If you read Day and the other progressive journals you will know that in some quarters of the galaxy there is considerable prejudice directed against us. It is ever so with minority races, and I do not complain. I merely make this statement so that you will understand about the alarm clock. An alarm clock...

THE COMING OF THE LOYALISTS

The vanguard of the Loyalists now began to make its appearance. Captain Simon Baxter has a fair claim to be considered the pioneer Loyalist of this province. He arrived at Fort Howe with his family in March, 1782, in distressed circumstances, and was befriended by William Hazen and James White, who recommended him to the favorable consideration of the authorities at Halifax. Captain Baxter was a native of New Hampshire. He was proscribed and banished on account of his loyalty, and had several narrow escapes at the hands of his “rebel countrymen.”On one occasion he was condemned to be...

AT THE CLOSE OF THE REVOLUTION— AFFAIRS CIVIL AND RELIGIOUS

After the establishment of Major Studholme’s garrison at Fort Howe, in the fall of 1777, the settlers on the river found adequate protection. The Indians occasionally assumed a hostile attitude it is true, especially when they were stirred up by Allan’s emissaries from Machias, but they were rather overawed by the proximity of the fort and were for the most part peacefully disposed. The privateers continued their depredations on the coast, but kept clear of Fort Howe. The condition of the settlers on the river had gradually improved and they were now able to live within themselves. Money too...

PIONEERS ON THE ST. JOHN RIVER IN PRE-LOYALIST DAYS

Considerable information has already been given in the preceding chapters of this history concerning the first English settlers on the River St. John, and the names of such men as Francis Peabody, Israel Perley, James Simonds, James White, William Hazen, Jonathan and Daniel Leavitt, Beamsley P. and Benjamin Glasier, Benjamin Atherton, William Davidson, Gilfred Studholme and others will be familiar to the majority of our readers. Some further information concerning the early settlers may prove of equal interest. BECKWITH. Nehemiah Beckwith was an active and well known man on the St. John river in his day and generation. He...

MASTS FOR THE ROYAL NAVY

The enormous lumbering operations carried on upon the St. John river and its tributaries in modern times had their small beginning, two centuries ago, when masts for the French navy were cut by order of the King of France.[114] The war of the Revolution obliged the English government to look for a reserve of trees suitable for masts in the remaining British colonies. In the year 1779, arrangements were made with William Davidson to provide a number of masts at the River St. John. Colonel Francklin was quite aware of the necessity of giving careful attention to the Indians...

WHITE CHIEFS AND INDIAN CHIEFS

In the year 1779 many of the Indians at Machias and Passamaquoddy began to waver in their adherence to the Americans and to imagine they would fare better by withdrawing from John Allan and returning to their old haunts on the River St. John. Allan wrote in the autumn of this year, “The unsteady conduct of the Indians has obliged me to use every means to prevent their going to St. Johns. I have not met with such difficulty previous to this summer.” He managed to keep them a little longer, but in July of the next year came...

THE GREAT INDIAN POW-WOW AT FORT HOWE, AND ITS CONSEQUENCES

The establishment of Fort Howe rendered the situation of the people at the mouth of the St. John comparatively secure, but the following summer was a very anxious and trying time to those who lived in the townships up the river. The Indians were restless and dissatisfied. They complained bitterly of being left without a missionary, and it was in vain that Lieut. Gov. Arbuthnot and Colonel Franklin endeavored to keep them in good temper by promising that a missionary would be sent them immediately. Most of the settlers in the townships were natives of New England, and the...

AFFAIRS ON THE ST. JOHN DURING THE REVOLUTION

In the year 1775 armed vessels were fitted out in several of the ports of New England to prey on the commerce of Nova Scotia. Many of these carried no proper commissions and were manned by hands of brutal marauders whose conduct was so outrageous that even so warm a partizan as Col. John Allan sent a remonstrance to congress regarding their behaviour: “Their horrid crimes,” he says, “are too notorious to pass unnoticed,” and after particularizing some of their enormities he declares “such proceedings will occasion more Torys than a hundred such expeditions will make good.” The people...

ON THE EVE OF THE AMERICAN REVOLUTION

When the county of Sunbury was established in 1765, there was no English settlement north of St. Ann’s and the river was but sparsely settled from that place to the sea. Nevertheless the immense forest wealth of the St. John was gradually becoming known and appreciated. The French ship of war “Avenant,” as long ago as the year 1700, after discharging her cargo of supplies for Villebon’s garrison and goods for the French traders, took on board some very fine masts for the French navy that had been cut upon the River St. John. Afterwards, when the control of...

SOME EARLY RELIGIOUS TEACHERS ON THE RIVER ST. JOHN

Our knowledge of affairs on the River Saint John down to the period of English occupation is largely derived from the correspondence of the Jesuit missionaries, the last of whom was Charles Germain. After his retirement the Acadians and Indians remained for several years without any spiritual guide, a circumstance that did not please them and was also a matter of concern to the Governor of Nova Scotia, who in December, 1764, informed the Secretary of State that a promise had been made the Indians of the River St. John to send them a priest, which the Lords of...

THE FIRM OF HAZEN, JARVIS, SIMONDS & WHITE

The circumstances under which James Simonds, William Hazen and their associates organized the first trading company at St. John have been already related. Their business contract was signed on the 1st of March, 1764. In the course of a year or two the character of the original company was essentially altered by the death of Richard Simonds, the retirement of Samuel Blodget and Richard Peaslie and the admission of Leonard Jarvis as a new partner. Questions had also arisen as to the rights of the several partners in the lands granted in 1765 to James Simonds, James White and...

THE ST. JOHN’S RIVER SOCIETY

Since the preceding chapters were printed the author chanced to discover some interesting manuscripts in the collections of the Massachusetts Historical Society which throw a good deal of light upon the history of the old townships on the River St. John. It is to be regretted that this discovery was not made a little sooner, but it is not too late to give the reader the benefit of it in a supplementary way. The association that undertook the settlement of the townships of Conway, Gage, Burton, Sunbury and New-town has been referred to in these pages as “The Canada...

NATIONALITY AND RACE FROM AN ANTHROPOLOGIST'S POINT OF VIEW

It was during the lifetime of Robert Boyle that our forefathers began to come into close contact with the races and nationalities of the outer world. When he was born in County Cork in the year 1627, small and isolated bands of Englishmen were elbowing Red Indians from the eastern sea-board of North America; before his death in London in 1691, at the age of sixty-four, he had seen these pioneer bands become united into a British fringe stretching almost without a break from Newfoundland to Florida. Neither he nor any one else in England could then have guessed...

PEOPLE OF AFRICA

It is hoped that this book and its companion volume dealing with non-African peoples will be the beginning of a series of simple, readable accounts for Africans of some of the various objects of general interest in the world of to-day. There are many such works published for the use of English and American children. But the native African has a totally different experience of life, and much that is taken for granted by a child of a Northern civilized land .needs explanation to one used to tropical uncivilized surroundings. Again, the African knows the essential operations of everyday life...

Tombs in The Stone Age

The true history of man will be found in his tombs, says Thucydides; and as a matter of fact the sepulchre has ever occupied much of the thoughts of man, the result of a religious sentiment, a conviction that all does not end with the life which so quickly passes by. From the very earliest times we meet with tokens of the hopes and fears connected with a future existence; but, as I have already stated, the human bones that can with certainty be said to date from Palæolithic times are very rare. We know but very few facts...

The Stone Age: its Duration and its Place in Time

The nineteenth century, now nearing its close, has made an indelible impression upon the history of the world, and never were greater things accomplished with more marvellous rapidity. Every branch of science, without exception, has shared in this progress, and to it the daily accumulating information respecting different parts of the globe has greatly contributed. Regions, previously completely closed, have been, so to speak, simultaneously opened by the energy of explorers, who, like Livingstone, Stanley, and Nordenskiöld, have won immortal renown. In Africa, the Soudan, and the equatorial regions, where the sources of the Nile lie hidden; in Asia,...

Camps, Fortifications, Vitrified Forts; Santorin; The Towns upon the Hill of Hissarlik

Combativeness, to use the language of phrenology, is one of the most lively instincts of humanity. The Bible tells us of the struggle between the sons of Adam, and shows us might making right ever since the days of primeval man. History is but one long account of wars and conquests, victories or defeats, and progress is chiefly marked in inventions which made battles more sanguinary and added to the number of victims slaughtered. At the very dawn of humanity man learned to make weapons; very soon, however, weapons ceased to appear sufficient. The first fortification was doubtless the...

Industry, Commerce, and Social Organization; Fights, Wounds and Trepanation

When we consider the discoveries connected with the Stone age as a whole, we are struck with the immense numbers of weapons of every kind and of every variety of form found in different regions of the globe. The Roman domination extended over a great part of the Old World, and it lasted for many centuries. Everywhere this people, illustrious amongst the nations, has left tokens of its power and of its industry. Roman weapons, jewelry, and coins occupy considerable spaces in our museums; but numerous as are these relics of the Romans, they are far inferior in number...

Megalithic Monuments

Megalithic monuments are perhaps the most interesting of all the witnesses of the remote past, into the history of which we are now inquiring, and of which so little is known. From the shores of the Atlantic to the Ural Mountains, from the frontiers of Russia to the Pacific Ocean, from the steppes of Siberia to the plains of Hindustan, we see rising before us monuments of the same characteristic form, built in the same manner. This is a very important fact in the history of humanity, and of which it is difficult to exaggerate the importance. What is...

Caves, Kitchen-Middings, Lake Stations, “Terremares,” Crannoges, Burghs, “Nurhags,” “Talayoti,” and “Truddhi”

The earliest races of men lived in a climate less rigorous than ours, on the shores of wide rivers, in the midst of fertile districts, where fishing and the chase easily supplied all their needs. These races were numerous and prolific, and we find traces of them all over Western Europe, from Norfolk to the middle of Spain. What were the homes of these men and their families? Did they crouch in dens, as Tacitus says the German tribes did in his day? In his “Ancient Wiltshire,” Sir R. Coalt Hoare says that the earliest human habitations were holes...

Weapons, Tools, Pottery; Origin of the Use of Fire, Clothing, Ornaments; Early Artistic Efforts

The Vedas show us Indra, armed with a wooden club, seizing a stone with which to pierce Vritra, the genius of evil.1 Does not this call up a picture of the earliest days of man upon the earth? His first weapon was doubtless a knotty branch torn from a tree as be hurried past, or a stone picked up from amongst those lying at his feet. These were, however, but feeble means with which to contend with formidable feline and pachydermatous enemies. Man bad not their great physical strength; he was not so fleet a runner as many of...

Food, Cannibalism, Mammals Fish, Hunting, and Fishing in The Stone Age

The first care of man on his arrival upon the earth was necessarily to make sure of food. Wild berries, acorns, and ephemeral grasses only last for a time, whilst land mollusca and insects, forming but a miserable diet at the best, disappear during the winter. Meat must certainly have been the chief food of prehistoric man; the accumulations of bones of all sorts in the caves and other places inhabited by him leave no doubt on that point. The horse, which in Europe was hunted, killed, and eaten for many centuries before it was domesticated, was an important...
