The movement authority packet defines a maximum speed that may be used for a given maximum distance and maximum time-setting the maximum speed to zero on a variable balise will make the train to stop.

If more information needs to be transmitted, then a third or fourth balise can be installed.

If the telegram maximum of 830 bits is reached then more packets can be sent in the following balises of the same balise group-with up to 8 balises in a balise group the maximum ERTMS message per balise group can encompass 8 * 830

In response to radio frequency energy broadcast by a Balise Transmission Module mounted under a passing train, the balise either transmits information to the train (' Uplink ') or receives information from the train (' Downlink ,' this function is rarely used ).

A balise transmits a ' telegram ' of either 1023 bits ( 93 * 11 ) or 341 bits ( 31 * 11 ) in the channel encoding with 11 bit per symbol.

The ERTMS Header block of 50 bit contains the ETCS version, the current number and total count of balises within a balise group ( up to 8 balises ), a flag whether it is a copy ( up to 4 copies ) that increases chances for the receiver to see the telegram of the balise in a group, a serial number flagging whether the message has changed lately, a 10-bit country identifier along with the 14-bit balise group identifier allowing for a unique ID of every balise group.

A fixed balise is programmed to transmit the same data to every train.

A controllable balise is connected to a Lineside Electronics Unit ( LEU ), which transmits dynamic data to the train, such as signal indications.

The data in the balise also includes the distance to the next balise.

Thus a fixed balise can notify a train of its exact location, and the distance to the next signal, and can warn of any speed restrictions.

A train travelling in the normal direction will meet the fixed balise and then the switchable balise.

A train travelling at maximum speed of 500 km / h will transmit and receive a minimum of three copies of the telegram while passing over the balise.

The telegram is broadcast in a cyclic manner as the train passes over the balise.

If a train will see balise 1 before balise 2 then it runs in nominal direction.

The required link information informs about the distance to the next balise group ( one link packet per direction ) and the required train reaction if the next balise is missed ( e. g. train stop ).

A balise which complies with the European Train Control System specification is called a Eurobalise.

Other features include auto turnback and a balise system, called PSM ( precision stop marker ).

Each pair of balises consist of a switchable balise and a fixed balise.

`` The accommodations may not be the poshest, but man!!

The race problem has tended to obscure other, less emotional, issues which may fundamentally be even more divisive.

Accounts have been published of Northern liberals in the South up against segregationist prejudice, especially in state-supported universities where pressure may be strong to uphold the majority view.

Nevertheless, it may be helpful to cite one example -- that of employment -- for, as will be shown below, it cuts across both facets of the new concept.

A measure of its widespread acceptance may be derived from a statement of the International Congress of Jurists in 1959.

Recognizing that the Rule of Law is `` a dynamic concept which should be employed not only to safeguard the civil and political rights of the individual in a free society '', the Congress asserted that it also included the responsibility `` to establish social, economic, educational and cultural conditions under which his legitimate aspirations and dignity may be realized ''.

While there may still be many Faulknerian Lucas Beauchamps scattered through the rural South, such men appear to be a vanishing breed.

or it may involve more subtle distinctions: the sway may be gradually minimized or enlarged, its rhythmic emphasis may be slightly modified, or it may be transferred to become a movement of only the arms or the head.

The approach to the depiction of the experience of creation may be analytic, as it is for Miss Litz, or spontaneous, as it is for Merle Marsicano.

The extent of such interference -- which may be so slight as to be undetectable at any point where either of the stations renders a usable signal, or may be so great as to virtually destroy the service areas of both stations -- depends on many factors, among the principal ones being the distance between the stations, their respective radiated power, and, of particular significance here, the time of day.

It is possible, of course, to work on extant or projected buildings where either architect or owner will explain their necessities so that the student may get `` the feel '' of real interior design demands.

The operand need not extend across the entire operand column of either the header card or continuation cards but may end with the comma following any parameter.

Evaluation may be made on either a soil-removal or a grease-removal basis as desired.

The electron optical system may be either a magnetic or electrostatic one.

Though it may exist in either literate or illiterate societies, it assumes a role of true cultural importance only in the latter.

Students of the college who are candidates for the A.B. degree and can satisfy the academic requirements of the medical and business schools, may enter either of these associated schools at the beginning of senior year, thus completing the two-year postgraduate course in one year.

We may now take up for consideration a hard case which seems to require either no action employing economic pressure or else action that would seem to violate the principles set forth above.

the attitude adopted by realtors and their associations, either negative or positive, plays a large part in the public acceptance of such measures and the degree to which they may be effectively enforced.

The jacket biography describes him as a former racing driver, and he may indeed have been, although I do not recall having encountered his name either in the records or the literature.

Some jurisdictions allow force to be used in defense of property, to prevent damage either in its own right, or under one or both of the preceding classes of defense in that a threat or attempt to damage property might be considered a crime ( in English law, under s5 Criminal Damage Act 1971 it may be argued that the defendant has a lawful excuse to damaging property during the defense and a defense under s3 Criminal Law Act 1967 ) subject to the need to deter vigilantes and excessive self-help.

The Nordendorf fibula ( early 7th century ) clearly records pagan theonyms, logaþorewodanwigiþonar read as " Wodan and Donar are magicians / sorcerers ", but this may be interpreted as either a pagan invocation of the powers of these deities, or a Christian protective charm against them.

In Luke 1: 3-4, the author states that he decided to “ write an orderly account for you, most excellent Theophilus, so that you may know the truth concerning the things about which you have been instructed .” Theophilus is Greek for lover of God and it is suggested that he may either be an individual who recently converted to the faith or a Roman official of whom the church is seeking acceptance from.

Pervo sees Luke ’ s work as a “ legitimizing narrative ” because it makes “ a case by telling a story ( or stories )” and serves to legitimate either “ Pauline Christianity ( possibly in rivalry to other interpretations ) or generally as the claim of the Jesus-movement to possess the Israelite heritage .” On the other hand, some scholars greatly disagree with the view of legitimation because they believe that it “ mirror-reads ” Luke ’ s work attempting to uncover the circumstances surrounding Luke ’ s work by over-arguing something that may not be that valid.
